Abstract

A rapid, efficient, convenient and cost-effective procedure has been developed for the synthesis of 3, 5-bis-(arylmethylidene)-tetrahydropyran-4-ones by the condensation of tetrahydropyran-4-one with araldehydes in the presence of catalytic amount of iodine to obtain the products in good to excellent yield. The reactions work at 25° C and go to completion within 30–60 min.
