Herein, we report a general, efficient and solvent-free method for the one-pot synthesis of allylic esters via dehydrogenation of unactivated alkanes and subsequent oxidative cross coupling with different substituted carboxylic acids. A simple, well defined and air stable Cu(II)-complex, [Cu(MeTAA)], featuring a tetraazamacrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)) is used as the catalyst. A wide variety substituted allylic esters were synthesized in high yields starting from readily available starting materials. Control reactions were carried out to understand the reaction sequence and the plausible mechanism.

Ri; Cho, Hoon] Chosun Univ, Dept Polymer Sci & Engn, Gwangju 61452, South Korea; [Choi, Dubok] B K Co Ltd, Biotechnol Lab, Jeonbuk 5703, South Korea published Synthesis, Structural Analysis, and Biological Evaluation of Novel ((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl Derivatives in 2020, Cited 28. Computed Properties of C10H12O2. The Name is 2-Phenylbutanoic acid. Through research, I have a further understanding and discovery of 90-27-7.

The objective of this study was to evaluate the synthesis, structural analysis, and biological effects of novel ((2, 4-dioxothiazolidin-5-ylidene)methyl)phenyl derivatives. The efficacy of 15-PGDH inhibition increased for the substituents in the derivatives in the order: cyclohexylpropyl > cyclohexylethyl > cyclohexylmethyl > cyclohexyl. Compound 12 inhibited 15-PGDH activity by binding to the amino acids Ile 214, Ile 210, Ile 194, Gln 148, and Leu 191 of 15-PGDH. Compounds 4, 22, and 23 produced the highest increment in PGE(2) concentration, which was 122.19, 100.14, and 206.80%, respectively, compared to that of the control. Also, compounds 38 and 39, in which the central phenyl ring and the 2, 4-thiazolidinedione moiety were linked by a single bond, produced a relatively high increment in PGE(2) concentration, which was 106.81 and 118.66%, respectively, compared to that of the control. The wound closure rates of compounds 22 and 39 were the highest, being 247.56 and 202.42%, respectively, compared to that of the positive control. Therefore, compounds 22 and 39 could not only efficiently regulate PGE(2) concentration, but also induce cellular regeneration, and are expected to effectively treat a variety of diseases resulting from PGE(2) deficiency.

Petal blight caused by fungi is among the most destructive diseases of Rhododendron, especially Rhododendron agastum. Nonetheless, the metabolite changes that occur during petal blight are unknown. We used untargeted gas chromatography time-of-flight mass spectrometry (GC-TOF-MS) and ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) to compare the metabolite profiles of healthy and petal blight R. agastum flowers. Using GC-TOF-MS, 571 peaks were extracted, of which 189 metabolites were tentatively identified. On the other hand, 364 and 277 metabolites were tentatively identified in the positive and negative ionization modes of the UHPLC-QTOF-MS/MS, respectively. Principal component analysis (PCA) and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) were able to clearly discriminate between healthy and petal blight flowers. Differentially abundant metabolites were primarily enriched in the biosynthesis of specialized metabolites. 17 accumulated specialized metabolites in petal blight flowers have been reported to have antifungal activity, and literature indicates that 9 of them are unique to plants. 3 metabolites (chlorogenic acid, medicarpin, and apigenin) are reportedly involved in resistance to blight caused by pathogens. We therefore speculate that the accumulation of chlorogenic acid, medicarpin, and apigenin may be involved in the resistance to petal blight. Our results suggest that these metabolites may be used as candidate biocontrol agents for the control fungal petal blight in Rhododendron.

We report a highly enantioselective catalytic protonation of bis-silyl ketene acetals. Our method delivers alpha-branched carboxylic acids, including nonsteroidal anti-inflammatory arylpropionic acids such as Ibuprofen, in high enantiomeric purity and high yields. The process can be incorporated in an overall deracemization of alpha-branched carboxylic acids, involving a double deprotonation and silylation followed by the catalytic asymmetric protonation.

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.

A Cu-based homogeneous catalytic system was proposed for the preparation of imides from alkene-tethered amides. Here, O-2 acted as a terminal oxidant and a cheap and easily available oxygen source. The cleavage of C=C bonds and the formation of C-N bonds were catalyzed by Cu(ii) salts with proper nitrogen-containing ligands under 100 degrees C. The synthesis approach has potential applications in pharmaceutical syntheses. Moreover, scaled-up experiments confirmed the practical applicability.

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.

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).

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.
