Cross-aldol condensation is a powerful tool for the formation of carbon–carbon bond in many classes of carbonyl compounds [1]. Also cross-aldol condensation is an effective pathway for the preparation of methylene structural unit, which is found in many naturally occurring compounds and antibiotics, and α,α′-bis(substituted benzylidene)cycloalkanones which are the important intermediates for the synthesis of pyrimidines [2]. ... The aldol reaction is catalyzed by ...
