Free Radical Cyclization of Thionocarbonic Acid Derivatives of 4-Phenyl-3-butenol: A New Route to Thionolactones
Treatment of various thionocarbonic acid derivatives of 4-phenyl-3-butenol with tri-n-butyltin hydride and AIBN in boiling benzene provides thionolactones and lactones in good yields via a free radical chain reaction.
