We report the first example of catalytic asymmetric Morita‐Baylis‐Hillman reaction of acrolein with aromatic aldehydes. The use of 10 mol% of Hatakeyama's catalyst β‐isocupreidine C4, in combination with 20 mol% of 2,6‐dimethoxybenzoic acid, could catalyze the reaction to give the desired products in up to 81% ee.
我们报道了丙烯醛与芳族醛的催化不对称森田-贝利斯-希尔曼反应的第一个例子。结合使用10 mol%的Hatakeyama催化剂β-异cupreidine C4和20 mol%的2,6-二甲氧基苯甲酸,可以催化反应,以最高81%ee的比例得到所需的产物。
