A synthetic approach to isomerically functionalized piperidine systems has been designed by intramolecular nitrone cycloaddition, starting from β-enamidoaldehydes, and by subsequent reductive ring-opening of the obtained fused δ-lactams.
通过从β-烯醛醛开始的分子内硝酮环加成,以及随后的所得稠合的δ-内酰胺的还原性开环,已经设计了异构化的官能化哌啶系统的合成方法。
