A new and efficient method for the reduction of α,β-unsaturated carboxylic esters to allylic alcohols utilizing LiAlH4/BnCl is described. Various α,β-unsaturated esters, including the coumarins bearing α,β-unsaturated lactone skeleton, can be converted smoothly into their corresponding allylic alcohols in high yields under mild conditions with short reaction times.
描述了一种利用LiAlH 4 / BnCl将α,β-不饱和羧酸酯还原为烯丙基醇的新的有效方法。各种带有α,β-不饱和内酯骨架的香豆素在内的各种α,β-不饱和酯可以在温和的条件下以短的反应时间,高收率平稳地转化为相应的烯丙醇。
