Catalytic asymmetric Mannich-type reactions using a novel chiral iron complex have been developed. The reactions proceeded smoothly in the presence of a catalyst prepared from iron(II) chloride, a BINOL derivative, and i-Pr2NEt. The desired products were obtained in good yield with good to high enantioselectivity, when 3,3′-I2BINOL was employed as a chiral ligand. A protic additive such as methanol
已经开发了使用新型手性铁配合物的催化不对称曼尼希型反应。在由氯化铁(II),BINOL衍生物和i -Pr 2 NEt制备的催化剂存在下,反应平稳进行。当使用3,3'-I 2 BINOL作为手性配体时,以良好的产率和良好的对映选择性获得了所需的产物。质子添加剂如甲醇有效地促进了反应。
