Synthesis of cis‐3‐methyl‐4‐aminopiperidine Derivatives
摘要:
A facile approach for the preparation of cis-3-methyl-4-aminopiperidine derivatives is described. The synthesis was carried out via regioselective ring opening of N-benzyl-3-methyl-3,4-epoxi-piperidine (8), which can be easily obtained in two steps from the corresponding N-benzyl-pyridinium salt (5). Seven new cis-3-methyl-4-amino and amido piperidines compounds were obtained.
