A dramatic acceleration of the enantioselective copper-catalyzed conjugate reduction of alpha,beta-unsaturated lactones, lactams, and esters is reported upon addition of alcohol additives. Good to excellent yields and enantioselectivities were realized using a catalyst generated in situ from CuCl(2).H(2)O, t-BuONa, p-tol-BINAP, and PMHS, and this methodology was applied to the synthesis of (-)-Paroxetine
据报道,在添加醇添加剂后,α、β-不饱和内酯、内酰胺和酯的对映选择性铜催化共轭还原显着加速。使用由 CuCl(2).H(2)O、t-BuONa、p-tol-BINAP 和 PMHS 原位生成的催化剂实现了良好到优异的产率和对映选择性,并且该方法用于合成 (- )-帕罗西汀。
