Asymmetric induction is observed in the additioin of chlorine to alkenes as well as in the synthesis of 0-acetyl cyanohydrins under phase-transfer conditions using (−)-benzylcinchonidinium chloride and (−)-N-dodecyl-N-methylephedrinium bromide as chiral catalysts.
使用(-)-苄基金鸡宁鎓氯化物和(-)-N-十二烷基-N-甲基麻黄碱溴化物作为手性催化剂,在相转移条件下,氯与烯烃的加成反应以及0-乙酰基氰醇的合成中观察到不对称诱导。 。
