In chiral alcohols bearing a phenylthio group at the β carbon atom. the hydroxy group is replaced by nitriles through the anchimeric assistance of the phenylthio group to afford chiral amides with retention of configuration. This stereospecific Ritter-type reaction has been utilized in the conversion of chiral glycidol derivatives to chiral cyclic imino ethers such as oxazolines bearing an arylthio
在β碳原子上带有苯硫基的手性醇中。通过苯硫基的手性辅助,羟基被腈取代,得到保留构型的手性酰胺。该立体有规的Ritter型反应已用于手性缩水甘油衍生物向手性环状亚氨基醚如带有芳硫基的恶唑啉的转化中。
