can be prepared by the catalytic enantioselective cross-aldol reaction of acetone with trihalomethyl ketones by using N-(8-quinolinesulfonyl)prolinamide as an organocatalyst. The MO calculations elucidate that the hydrogen bonding between the sulfonimide proton and the 8-quinolyl nitrogen atom plays an important role in exerting the enantioselectivity of the reaction.
可以通过使用N-(8-喹啉磺酰基)脯氨酰胺作为有机催化剂,通过丙酮与三卤代甲基酮的催化对映选择性交联醇醛缩合反应来制备具有季手性碳中心的对映体富集的三卤代甲基取代的醇。MO计算表明,磺酰亚胺质子和8-喹啉基氮原子之间的氢键在施加反应的对映选择性方面起重要作用。
