The transformations of unactivated alkenes through C & xe001;C bond double cleavage are always attractive but very challenging. We report herein a chemoselective approach to valuable cyclic imides by a novel Cu-catalyzed geminal amino-oxygenation of unactivated C & xe001;C bonds. O-2 was successfully employed as the oxidant as well as the O-source and was incorporated into alkenyl amides via C & xe001;C bond cleavage for the efficient preparation of succinimide or glutarimide derivatives. Moreover, the present strategy under simple conditions can be used in the late-stage modification of biologically active compounds and the synthesis of pharmaceuticals, which demonstrated the potential application.

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).

Reductive N-O bond cleavage has been widely explored for providing either N or O radical species for various coupling processes. Despite significant advances, this photoredox pathway is less appealing due to poor atom economy owing to the loss of one fragment during the transformation. In this regard, the homolytic N-O bond cleavage by an energy-transfer pathway to provide two key radicals would be highly desirable for overcoming the limitations of the use of one fragment. We report an exclusive energy-transfer approach for the development of a challenging radical-radical C(sp(3))-N cross-coupling process by reactivity-tuning of the catalytic system. The homolytic N-O bond cleavage of oxime esters in the presence of an Ir complex produces acyloxy and iminyl radicals, which undergo decarboxylative cross-coupling to yield valuable imines (typically 0.25 mol % cat. and 1 h reaction time). Extensive photophysical and electrochemical measurements, as well as density functional theory studies, were carried out to probe the mechanism and the operation of a Dexter-type energy-transfer pathway was revealed. The choice of solvent (EtOAc) and reaction concentration were critical for achieving the selectivity and reactivity in this cross-coupling process. The synthetic utility of this method was explored by studying highly functionalized oxime esters, including derivatives of biologically active natural products and drug molecules. Furthermore, in situ transformations of the imine products into pharmaceutically important amines were also demonstrated, showcasing the utility of the imine products as valuable amine building blocks.

A dual experimental/theoretical investigation of the Ireland-Claisen rearrangement of tetrasubstituted alpha-phthalimido ester enolates to afford alpha-tetrasubstituted, beta-trisubstituted alpha-amino acids (generally >20:1 dr) is described. For trans allylic olefins, the Z- and E-enol ethers proceed through chair and boat transition states, respectively. For cis allylic olefins, the trend is reversed. As a result, the diastereochemical outcome of the reaction is preserved regardless of the geometry of the enolate or the accompanying allylic olefin. We term this unique convergence of all possible olefin isomers global diastereoconvergence. This reaction manifold circumvents limitations in present-day technologies for the stereoselective enolization of alpha,alpha-disubstituted allyl esters. Density functional theory paired with state-of-the-art local coupled-cluster theory (DLPNO-CCSD(T)) was employed for the accurate determination of quantum mechanical energies.

Chiralpak ZWIX(+) and ZWIX(-), are brush-type bonded-silica chiral stationary phases (CSPs), based on complex diastereomeric Cinchona alkaloids derivatives bearing both a positive and a negative charge. In the present study, we aimed to improve the understanding of retention and enantioseparation mechanisms of these CSPs employed in supercritical fluid chromatography (SFC). For this purpose, 9 other stationary phases were used as comparison systems: two of them are commercially available and bear only a positive charge (Chiralpak QN-AX and QD-AX) and the 7 others were designed purposely to be structurally similar to the parent ZWIX phases, but miss some portion of the complex ligand. First, cluster analysis was employed to identify similar and dissimilar behavior among the 11 stationary phases, where ionic interactions appeared to dominate the observed differences. Secondly, the stationary phases were characterized with linear solvation energy relationships (LSER) based on the SFC analysis of 161 achiral analytes and a modified version of the solvation parameter model to include ionic interactions. This served to compare the interaction capabilities for the 11 stationary phases and showed in particular the contribution of attractive and repulsive ionic interactions. Then the ZWIX phases were characterized for their enantioseparation capabilities with a set of 58 racemic probes. Discriminant analysis was applied to explore the molecular structural features that are useful to successful enantioseparation on the ZWIX phases. In particular, it appeared that the presence of positive charges in the analyte is causing increased retention but is not necessarily a favorable feature to enantiorecognition. On the opposite, the presence of negative charges in the analyte favors early elution and enantiorecognition. Finally, a smaller set of 30 pairs of enantiomers, selected by their structural diversity and different enantioseparation values on the ZWIX phases, were analyzed on all chiral phases to observe the contribution of each structural fragment of the chiral ligand on enantioselectivity. Molecular modelling of the ligands also helped in understanding the three-dimensional arrangement of each ligand, notably the intra-molecular hydrogen bonding or the possible contribution of ionic interactions. In the end, each structural element in the ZWIX phases appeared to be a significant contributor to successful enantioresolution, whether they contribute as direct interaction groups (ion-exchange functions) or as steric constraints to orientate the interacting groups towards the analytes.

2-Phenylbutanoic acid (2PBA) and its functional derivatives 2-amino-2-Phynylbutanoic acid (2APBA), 2-hydroxy-2-Phenylbutanoic acid (2HPBA) and 2-methyl-2-phenylbutanoic acid (2MPBA) are analyzed by density functional theory (DFT) calculations at B3LYP level with basis set 6-311++G(d,p). Experimental studies like FT-IR, FT-Raman, and UV-Visible spectra are carried out and compared with the theoretical molecular geometry and vibrational frequencies. To study donor and acceptor interactions natural bond orbital (NBO) analysis were performed. The observed UV-Vis spectrum compared with the time-dependent TD-DFT analysis gives band gap energies, oscillator strength, and the absorption wavelengths of different molecules. The hyperpolarizability analysis shows that the nonlinear optical (NLO) properties of the 2PBA, 2APBA, 2HPBA and 2MPBA compounds. The visual bio-active areas of the molecule are estimated by Molecular electrostatic potential (MEP). The important thermodynamic properties like heat capacity, entropy, and enthalpy of the 2PBA, 2APBA, 2HPBA, and 2MPBA were calculated at different temperatures. Molecular docking methods were employed with 2PBA, 2APBA, 2HPBA and 2MPBA molecules with the same set of receptors (proteins) to find the best of four molecules for drug identification.
