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 acid ethyl ester. The single isomer with the structural skeleton of 3,3-diarylazepan-4-one and 5,5-diarylazepan-4-one is constructed in two functional group transformations of Grignard addition/dehydration and epoxidation/pinacol rearrangement.
