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

Abstract

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.
