Ketene aminothioacetals

Z)-.S -Allylic ketene aminothioacetals underwent thio-Claisen rearrangement at room temperature to give iVjV-dimethyl /1-hydroxy a-allylic thioamides96. /3-I Iydroxy-/V,/V,-dimethylthioamides were deprotonated with LDA to afford a chelated dianion with Z-configuration. Alkylation of this dianion gave the corresponding Z a-hydroxy S-allylic... [Pg.735]
