Tandem Aza-Michael–Aldol Reactions: One-Pot Synthesis of Functionalized Piperidine Derivatives

摘要

A series of novel functionalized piperidine derivatives were conveniently prepared by three-component tandem aza-Michael–Aldol reactions of α,β-unsaturated enones with substituted sulfonamides in the presence of DBU. The structures of the compounds synthesized were characterized by spectral data and X-ray crystal diffraction.
