  Isolation and Characterization of Atropisomers of Seven-Membered-Ring Benzolactams

  摘要：

  The atropisomeric properties of seven-membered-ring benzolactams (7a-c and 8a) [1,5-benzodiazepin-2-one (a), 1,5-benzothiazepin-4-one (b), and 1-benzazepin-2-one (c)] were examined. The atropisomers were isolated as the diastereomers with an (S)-phenethylamide moiety, which were characterized by X-ray crystallography, and the barriers to their interconversion were clarified.

Here, we revisit this issue by examining the influence of secondary interactions on the stability and reactivity of the putative iminylium cation intermediates, formed by N–O bond cleavage of 1-tetralone oxime systems.
