The regioselectivity of the addition of α-substituted organocuprates to enals has been examined. The addition of trimethylsilyl chloride to both the enal and cuprate prior to the combination of the reactants improves the regioselectivity and the isolated yield for the 1,4-addition product.
已经研究了将α-取代的有机铜酸酯添加到烯醛中的区域选择性。在反应物结合之前,将三甲基甲硅烷基氯同时加入到烯醛和铜酸盐中,可提高区域选择性,并提高了1,4-加成产物的分离产率。
