The construction of carboxylic acid compounds in a selective fashion from low value materials such as alkenes remains a long-standing challenge to synthetic chemists. In particular, beta-addition to styrenes is underdeveloped. Herein we report a new electrosynthetic approach to the selective hydrocarboxylation of alkenes that overcomes the limitations of current transition metal and photochemical approaches. The reported method allows unprecedented direct access to carboxylic acids derived from beta,beta-trisubstituted alkenes, in a highly regioselective manner.

The 2-(neopentylsulfinyl)aniline directing group that promotes rapid palladium-catalyzed C-H acetoxylation and alkenylation of arylacetamides has been developed. The acetoxylation reaches completion within only 40 min at 100 degrees C and leads to the bis-functionalized products. Alternatively, the reaction can be carried out at room temperature, which is beneficial for sensitive substrates. For the alkenylation, we have developed a protocol in which easily available 1-substituted cyclopropanols were employed as equivalents of vinyl ketones.

Enzymatic stereodivergent synthesis to access all possible product stereoisomers bearing multiple stereocenters is relatively undeveloped, although enzymes are being increasingly used in both academic and industrial areas. When two stereocenters and thus four stereoisomeric products are involved, obtaining stereodivergent enzyme mutants for individually accessing all four stereoisomers would be ideal. Although significant success has been achieved in directed evolution of enzymes in general, stereodivergent engineering of one enzyme into four highly stereocomplementary variants for obtaining the full complement of stereoisomers bearing multiple stereocenters remains a challenge. Using Candida antarctica lipase B (CALB) as a model, we report the protein engineering of this enzyme into four highly stereocomplementary variants needed for obtaining four stereoisomers in transesterification reactions between racemic acids and racemic alcohols in organic solvents. By generating and screening less than 25 variants of each isomer, we achieved >90% selectivity for all of the four possible stereoisomers in the model reaction. This difficult feat was accomplished by developing a strategy dubbed focused rational iterative site-specific mutagenesis (FRISM) at sites lining the enzyme’s binding pocket. The accumulation of single mutations by iterative site-specific mutagenesis using a restricted set of rationally chosen amino acids allows the formation of ultrasmall mutant libraries requiring minimal screening for stereoselectivity. The crystal structure of all stereodivergent CALB variants, flanked by MD simulations, uncovered the source of selectivity.

Organic molecules bearing acetoxy moieties are important functionalities in natural products, drugs, and agricultural chemicals. Synthesis of such molecules via transition metal-catalyzed C-O bond formation can be achieved in the presence of a carefully chosen directing group to alleviate the challenges associated with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the carboxylate followed by rapid decarboxylation and oxidation by Cu(OAc)(2).

The yeast strain Moniliella spathulata SBUG-Y 2180 was isolated from oil-contaminated soil at the Tengiz oil field in the Atyrau region of Kazakhstan on the basis of its unique ability to use crude oil and its components as the sole carbon and energy source. This yeast used a large number of hydrocarbons as substrates (more than 150), including n-alkanes with chain lengths ranging from C-10 to C-32, monomethyl- and monoethyl-substituted alkanes (C-9-C-23), and n-alkylcyclo alkanes with alkyl chain lengths from 3 to 24 carbon atoms as well as substituted monoaromatic and diaromatic hydrocarbons. Metabolism of this huge range of hydrocarbon substrates produced a very large number of aliphatic, alicyclic, and aromatic acids. Fifty-one of these were identified by GC/MS analyses. This is the first report of the degradation and formation of such a large number of compounds by a yeast. Inoculation of barley seeds with M. spathulata SBUG-Y 2180 had a positive effect on shoot and root development of plants grown in oil-contaminated sand, pointing toward potential applications of the yeast in bioremediation of polluted soils.

A series of five new zinc(II) complexes of 2-phenylbutyric acid comprising of one homoleptic (1) and four heteroleptic (2-5) complexes were synthesized under open beaker conditions. The behavior of the complexes in the solid and solution state was explored through FT-IR and NMR (H-1 and C-13) spectroscopy, respectively. Crystallographic data have revealed that complexes 2 and 3 crystallized in monoclinic and triclinic crystal system, respectively, with a distorted octahedral geometry, whereas complex 4 crystallized in monoclinic crystal system with a pentagonal geometry around the zinc(II) atom. All the complexes have been screened for enzyme (alkaline phosphatase) inhibition, in vitro hemolysis and antileishmanial activity, DNA and cetyl-trimethylammonium bromide (CTAB) interaction. The increase in the concentration of complexes 1, 2, 4 and 5 remarkably decreases the activity of enzyme alkaline phosphatase, whereas complex 3 was found inactive. The behavior of the complexes as a potent drug is clear from the results of hemolysis and antileishmanial activity against promastigote. The UV-Vis spectroscopic data of complexes-DNA interactions suggested a surface binding mode whereas the interaction of CTAB with complexes, studied through conductometry, confirmed strong in-teracting ability of complexes with CTAB.

Safety of 2-Phenylbutanoic acid. Garcia-Lopez, D; Pavlovic, L; Hopmann, KH in [Garcia-Lopez, Diego; Pavlovic, Ljiljana; Hopmann, Kathrin H.] UiT Arctic Univ Norway, Hylleraas Ctr Quantum Mol Sci, Dept Chem, N-9037 Tromso, Norway published To Bind or Not to Bind: Mechanistic Insights into C-CO2 Bond Formation with Late Transition Metals in 2020, Cited 72.

In transition metal-mediated carboxylation reactions, CO2 inserts into a metal-nucleophile bond. At the carboxylation transition state (TS), CO2 may interact with the metal (inner-sphere path) or may insert without being activated by the metal (outersphere path). Currently, there is no consensus as to which path prevails. In order to establish general predictions for the insertion of CO2 into metal-carbon bonds, we computationally analyze a series of experimentally reported Cu, Rh, and Pd complexes. Our focus is on carboxylation of aromatic substrates, including C(sp)(3 )benzyl and C-sp(2) aryl and alkenyl nucleophiles. We observe clear trends, where the nature of the nucleophile determines the preferred path: benzylic C-sp(3), nucleophiles favor outer-sphere and C-sp, systems favor inner-sphere CO2 insertion into the metal-carbon bond. An exception are Cu-benzyl bonds, where inner- and outer-sphere CO2 insertions are found to be competitive, highlighting the need to include both paths in mechanistic studies and in the rationalization of experimental results. For insertion into Pd-C-sp2 bonds, we find that the metal-CO2 interactions at the TS are weak and may be beyond 3 angstrom for sterically congested ligands. Nonetheless, on the basis of a comparison to other TSs, we argue that the CO2 insertion into Pd-C(sp2 )bonds should be classified as inner-sphere.

Deuterium-labeled compounds find wide applications in kinetic studies, and within the pharmaceutical industry. An easily removable pyrimidine-based auxiliary has been employed for the meta-C-H deuteration of arenes. The scope of this Pd-catalyzed deuteration using commercially available [D-1]- and [D-4]-acetic acid has been demonstrated by its application in phenylacetic acid and phenylmethanesulfonate derivatives. A detailed mechanistic study led us to explore the reversibility of the non-rate determining C-H activation step. The present study of meta-deuterium incorporation illustrates the template morphology in terms of selectivity. The applicability of this method has been demonstrated by the selective deuterium incorporation into various pharmaceuticals.

Bambusa pervariabilis x Dendrocalamopsis grandis blight, caused by Arthrinium phaeospermum, is one of the most common and serious diseases in bamboo and occurs in the newly born twigs. Bamboo has suffered large dead areas, including more than 3000 hm(2), which greatly threatens the process of returning farmlands to forests and the construction of ecological barriers. To identify differential metabolites and metabolic pathways associated with B. pervariabilis x D. grandis to A. phaeospermum, ultra-performance liquid chromatography (UPLC) and quadrupole-time of flight (Q-TOF) Mass Spectrometry (MS) combined with a data-dependent acquisition method was used to analyse the entire sample spectrum. In total, 13223 positive ion peaks and 10616 negative ion peaks were extracted. OPLS-DA and several other analyses were performed using the original data. The OPLS-DA models showed good quality and had strong predictive power, indicating clear trends in the analyses of the treatment and control groups. Clustering and KEGG pathway analyses were used to screen the differential metabolites in the treatment and control groups from the three B. pervariabilis X D. grandis varieties and reflected their metabolic responses induced by A. phaeospermum infection. The results showed that the three B. pervariabilis x D. grandis varieties mode showed significant changes in the following six resistance-related metabolites after A. phaeospermum invasion in positive and negative ion modes: proline, glutamine, dictamnine, apigenin 7-O-neohesperidoside, glutamate, and cis-Aconitate. The following four main metabolic pathways are involved: Arginine and proline metabolism, Glyoxylate and dicarboxylate metabolism, Biosynthesis of alkaloids derived from shikimate pathway, and Flavone and flavonol biosynthesis. This study lays a foundation for the later detection of differential metabolites and metabolic pathways for targeting, and provides a theoretical basis for disease-resistant breeding and the control of B. pervariabilis x D. grandis blight.
