An efficient approach towards introducing (cyclo)alkyl substituents at C-2, C-3 or C-4 positions of the piperidine ring was described. The method relied on the straightforward two-step reaction sequence based on the formal sp3–sp3 re

A novel Pd-C catalytic hydrodechlorination-hydrogenation was developed for a multi-step one-pot transformation of 4-acylpyridines. Under the selected conditions, 4-benzoylpyridines and 4-alkanoylpyridines were chemoselectively converted into the corresponding 4-benzylpiperidine hydrochlorides and α-alkyl-4-piperidinemethanol hydrochlorides, respectively. This catalytic method was performed simply by an addition of 1 equiv of ClCH 2CHCl2 to the conventional hydrogenation system and directly gave the crystalline piperidine hydrochlorides in practical quantitative yields.
