摘要

Synthesis of new dihydrospiro[quinoline-2,4'-piperidines] by a two-step synthetic route based on 4-piperidone imine reactivity is reported. An acetyl migration in 1-acetyl-1'-benzyl-4-methyl-3,4- dihydrospiro[quinoline-2,4'-piperidines] under debenzylation conditions (HCOONH4 / Pd / C / MeOH) is found.
