exchange reaction leading to polyfunctional dialkylzincs. The catalytic asymmetric addition of these zinc reagents to a wide range of α,β-unsaturated aldehydes provides polyfunctional allylic alcohols with a high enantioselectivity.
催化量的Cu(I)盐极大地促进了碘-锌交换反应,从而形成了多官能的二烷基锌。将这些锌试剂催化不对称地添加到各种α,β-不饱和醛中,可提供具有高对映选择性的多官能烯丙基醇。
