First highly efficient synthesis of bis(arylmethylidene)pyranones mediated by lithium perchlorate
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.
