An efficient methodology for the enantioselective synthesis of γ-lactams, using a one-pot reaction of chiral N-alkoxycarbonyl γ-amino α,β-unsaturated carboxylates with magnesium in methanol, afforded the target chiral compounds in high chemical yield (87–95%) and optical purity (96–99% ee).
使用手性N-烷氧基羰基γ-氨基α,β-不饱和羧酸盐与镁在甲醇中的一锅反应,对映体选择性合成γ-内酰胺的有效方法,可以以高化学收率得到目标手性化合物(87-95 %)和光学纯度(96–99%ee)。
