The conjugate addition of chloride to chiral but-2-enoic imides promoted by BCl3-derivatives proceeds with diastereoisomeric ratios of up to 90 : 10 and affords the corresponding 3-chlorobutanoic imides from which, after mild hydrolysis, the 3-chlorobutanoic acid is obtained.
在BCl3衍生物的催化下,氯化物与手性丁-2-烯酰亚胺的共轭加成反应,其非对映异构体比率高达90:10,并生成相应的3-氯丁酰亚胺,经温和水解后,可得到3-氯丁酸。
