efficient one-pot synthesis of substituted piperidines was developed through nitroalkene, amine, and enone condensation. The transformation was suitable for a large group of substrates, giving excellent yields and diastereoselectivity. Reactions using chiral amines revealed a chirality induction through the unusual exocyclic stereochemistry control, producing enantiomeric pure piperidines in simple steps
