Au-catalyzed reaction of propargylic sulfides and dithioacetals

(Chemical Equation Presented) Propargylic sulfides and dithioacetals are found to undergo similar transformations as propargylic carboxylates when catalyzed by AuCl or AuCl3, affording indene derivatives through pentannulation of aromatic rings

A convenient synthesis of propargylic dithioacetals

Treatment of trimethylsilyl-substituted alkynyl ketones with 1,2-ethanedithiol in the presence of BF3·OEt2 in methanol afforded the corresponding dithioacetal. Removal of the silyl group under basic conditions followed by palladium-catalyzed coupling reactions with aryl iodides yielded the corresponding propargylic dithioacetals in excellent yield.
