Treatment of ω-amidosulfoxides with -silylated ketene acetals in dry acetonitrile in the presence of a catalytic amount of zinc iodide causes a novel intramolecular Pummerer-type rearrangement to give α-thio--heterocycles in high yields.
在催化量的碘化锌存在下,在干燥的乙腈中用甲硅烷基化的乙烯酮缩醛处理ω-氨基亚砜,引起新型的分子内Pummerer型重排,从而高产率地得到α-硫代-杂环。
