An expedient, five step synthesis of caprolactam 1 is reported starting from natural L-homoserine. The key step is a chemoselective reductive cyclization of α,β-unsaturated nitrile 10 mediated by Raney-Co type metals. This hydrogenation is extensively investigated in order to account for the observed product distribution and yields.
据报道,从天然的L-高丝氨酸开始,己内酰胺1的一种方便的五步合成方法。关键步骤是由Raney-Co型金属介导的α,β-不饱和腈10的化学选择性还原环化。为了考虑观察到的产物分布和产率,对该氢化进行了广泛的研究。
