A highly enantioselective domino reaction of α,β-unsaturated aldehydes and 4-acetyl-5-oxohexanal catalyzed by a chiral secondary amine catalyst has been developed, providing an efficient synthetic approach for the synthesis of densely functionalized chiral cyclohexene derivatives with high yields (up to 96%) and enantioselectivities (up to 97% ee) under mild conditions.
已开发出由手性仲胺催化剂催化的α,β-不饱和醛和4-乙酰基-5-氧己醛的高度对映选择性多米诺反应,为高密度合成高官能度的手性环己烯衍生物提供了一种高效的合成方法(up至96%)和对映体选择性(至多97%ee)在温和条件下。
