BiVO4 was found to be an efficient photocatalystundervisiblelight irradiation for selectiveoxidation of amines to imines with high activity (99% conversion) and selectivity (up to 99%) using oxygen as an oxidant.
The intramolecular carbene C–H insertion of α-diazo-α(methoxycarbonyl)acetamides leading to β-lactams is effectively catalyzed by palladiumcomplexes. It is found that whereas Pd(0)catalysts typically produce mixtures of β-lactams together with Buchner-type reaction products, the use of Pd(II)-catalysts results in highly chemoselective transformations. According to DFT calculations, this insertion reaction

Ni-catalyzed ligand-controlled tunable cyclization/cross-couplings was developed for the divergent synthesis of pharmacologically important 2-benzazepine frameworks. The bidentate ligand facilitates the formation of 2-benzazepin-5-ones and benzo[c]pyrano[2,3-e]azepines. The tridentate ligand promotes the formation of 2-benzazepin-3-ones.

NAD(P+/NAD(P)H Models. 83. Molecular Asymmetry with a Carbonyl Group: Electronically Controlled Stereochemistry in the Reaction of NAD(P)+/NAD(P)H Analogs
The N-methylpyridinium salt of 6,7,dihydro-6-methyl-5-oxopyridino[3,2-d]-2-benzazepin has been synthesized. The salt has axial chirality with respect to the orientation of the carbonyl dipole. An enantiomer of the cation has been obtained as the iodide salt. Reduction of the salt results in the corresponding dihydropyridine derivative stereospecifically. The stereochemistry of the reduction is controlled entirely by the electronic effect of the carbonyl dipole.
