The development of highly enantioselective and general catalytic nitroaldol (Henry) reactions with ketones is a challenging yet desirable task in organic synthesis. In this communication, we report an asymmetric nitroaldol reaction with alpha-ketoesters catalyzed by a new C6'-OH cinchona alkaloid catalyst. This is the first highly efficient organocatalytic asymmetric Henry reaction with ketones. This
与酮的高度对映选择性和通用催化硝基醛醇 (Henry) 反应的发展是有机合成中一项具有挑战性但理想的任务。在这篇通讯中,我们报告了一种由新的 C6'-OH 金鸡纳生物碱催化剂催化的与 α-酮酯的不对称硝基醛醇反应。这是第一个与酮的高效有机催化不对称亨利反应。该反应操作简单,对广泛的α-酮酯具有高对映选择性和良好的收率。
