Synthesis of diarylazepan-4-ones

Synthesis of several 3,3-diarylazepan-4-ones and 5,5-diarylazepan-4-ones has been established starting from two tetrasubstituted olefins, which is derived from commercially available piperidine-3-carboxylic acid ethyl ester and piperidine-4-carboxylic aci

CAN-mediated rearrangement of 4-benzhydrylidenepiperidines

Several 1-substituted phenyl-(4-phenylpiperidin-4-yl)methanones are synthesized in modest overall yields starting from the reaction of different 1-substituted 4-benzhydrylidenepiperidines via CAN-mediated rearrangement. This facile strategy was also used to synthesize meperidine analog.
