Lithium perchlorate-mediated double
crossed aldol condensations of a variety of aromatic aldehydes with
cycloalkanones at room temperature in the presence of (trimethylsilyl)diethylamine
and under solvent-free conditions are described. High to excellent yields of
bis(arylmethylidene)cyclohexanones and bis(arylmethylidene)cyclopentanones
are achieved within a few minutes in this facile one-pot procedure.
