摘要

Summary: Reactions of benzylic and allylic sulfides 1. having 5-mercapto-l-phenyl-lg-tetra- zolyl group with g-silylated ketone and ester enolates 2 in the presence of silver triflate gave coupling products 3 in good yield. (i)-ar-turmerone was synthesized by this method. - - Alkyl and allylic sulfides have been used widely as intermediates for the formations of carbon-carbon bonds. 1) Recently, we have reported the single-step preparations of benzylic and allylic sulfides ...
