Treatment of 3,4-epoxyamides with LDA affords γ-hydroxy-α,β-unsaturated amides, usually with high (E)-selectivity. The 3,4-epoxyamides were prepared by the epoxidation of β,γ-unsaturated amides with meta-chloroperbenzoic acid.
用LDA处理3,4-环氧酰胺可得到γ-羟基-α,β-不饱和酰胺,通常具有高(E)选择性。通过将β,γ-不饱和酰胺与间-氯过苯甲酸环氧化制备3,4-环氧酰胺。
