摘要：

A remarkably efficient double-crossed aldol condensation of tetrahydropyran-4-one with a variety of aromatic aldehydes is described at room temperature in the presence of (trimethylsilyl)diethylamine and lithium perchlorate under solvent-free conditions. Excellent yields of 3,5-bis(arylmethylidene)pyranones are achieved in a facile one-pot general procedure.
