Treatment of enolizable (methylthio)alkylideniminium salts with active methylene compounds under basic conditions gives Knoevenagel-type adducts in excellent yields.Attempts to convert several of these adducts to vinylogous urethanes and vinylogous amides met with varied success.One-pot preparations of vinylogous urethanes and vinylogous amides from (methylthio)alkylideniminium salts and selected active methylene compounds are also described.
