α-Phenylthio secondary propanamides 1a-e are converted stereospecifically on treatment with NCS to the analogous (Z)-α-phenylthio-β-chloro propenamides 2a-e. Extension to longer chain secondary amide derivatives 1f-g is also possible, albeit less efficiently and without any appreciable stereoselectivity.
在用NCS处理后,将α-苯硫基仲丙酰胺1a-e立体定向转化为类似的(Z)-α-苯硫基-β-氯丙烯酰胺2a-e。也可以延伸至长链仲酰胺衍生物1f-g,尽管效率较低且没有任何明显的立体选择性。
