摘要：

Thermal reaction of tributyl(cyclohepta-1,3,5-trienylimino)phosphorane with α,β-unsaturated ketones led to a Michael-type C-C bond formation and subsequent aza-Wittig reaction to give 9H-cyclohepta[b]pyridine derivatives in good yields. The 9H-cyclohepta[6]pyridine derivatives were oxidized conveniently by t-butyl hydroperoxide in the presence of catalytic chromium trioxide to give two or three isomers of the pyridotropones in good to moderate combined yields.
