An organocatalyst derived from quinine efficiently promoted an asymmetric Henry reaction between α,β -unsaturated trifluoromethyl ketones and nitromethane, resulting in corresponding and highly functionalized products with excellent yields and high enantioselectivities (up to 94% ee).
一种源自奎宁的有机催化剂有效地促进了 α,β-不饱和三氟甲基酮和硝基甲烷之间的不对称亨利反应,从而产生了相应的高度功能化的产物,具有优异的收率和高对映选择性(高达 94% ee)。
