摘要：

Thermal reaction of tributyl(inden-3-ylimino)phosphorane with alpha, beta-unsaturated ketones and aldehydes led to a Michael-type C-C bond formation and subsequent aza-Wittig reaction to give 5H-indeno(1,2-b)pyridines in good to modest yield. The products were oxidized conveniently by chromium trioxide and t-butyl hydroperoxide to give 5H-indeno[1,2-b]pyridin-5-ones, including the 4-azafluorenone alkaloid onychine.
