摘要 由天然樟脑和(L)-苯丙氨酸合成了4个新的手性磺酰胺醇,并对其在二乙基锌对苯甲醛的不对称加成中的催化性能进行了研究。这4个手性磺酰胺醇表现出中等程度的催化活性和较差的不对称诱导作用。 Four new chiral sulfonamide alcohols were synthesized from camphor and L-phenylalanine and their application to the enantioselective addition of diethylzinc to benzaldehyde was described. Sulfonamide alcohols were found to have moderate catalytic activity and weak asymmetric induction during the addition of diethylzinc to benzaldehyde.
