The first copper hydride (CuH)-catalyzed asymmetric 1,6-conjugate reduction of p-quinone methides is reported. This protocol provides a new method to access a variety of triarylmethanes and 1,1,2-triarylethanes in good yields with excellent enantioselectivities and broad functional group tolerance.
据报道,氢化铜(CuH)首次催化了对醌甲基化物的不对称1,6-共轭还原。该协议提供了一种新方法,可以以良好的收率获得优异的对映选择性和宽泛的官能团耐受性,以获取各种三芳基甲烷和1,1,2-三芳基乙烷。
