摘要：

gamma-Sulfur-substituted propargyl alcohols 1a-e and 1ij reacted with polyphosphoric acid trimethylsilyl ester (PPSE) to give the alpha,beta-unsaturated thioesters 3a-e and 3ij in good yields. However, the reactions of 3,3-dibutyl-1 -(phenylthio)propargyl alcohol (1k) and 1-(phenylthio)ethynyl- 1-cyclo alkanols 1l-n with PPSE gave the enyne sulfides 2k-n exclusively.
