摘要

Abstract α′, α′-Disilylated benzamides 2, prepared by LiTMP/TMSCl in situ trap procedure, constitute ortho-and α′-carbanion synthons which provide N-benzoyl enamines (5), isoquinolines (6), dibenzoazocines (9) by Peterson olefination, and pyrroles (11) by cycloaddition. The conversion of 2 into other useful functionality is described.
