A chlorination of optically active alkyl p-tolyl sulfoxides with N-chlorosuccinimide in dichloromethane in the presence of potassium carbonate afforded optically active 1-chloroalkyl p-tolyl sulfoxides in 87–94% ee (88–94% chemical yields). The optically active chloroalkyl sulfoxide was applied to a synthesis of optically active (+)-disparlure.
在碳酸钾存在下,在二氯甲烷中用N-氯代琥珀酰亚胺在N氯代琥珀酰亚胺中氯化旋光性烷基对甲苯基亚砜,可以得到87-94%ee(88-94%化学产率)的旋光性1-氯烷基对甲苯基亚砜。将光学活性的氯代烷基亚砜用于光学活性(+)-分散剂的合成。
