Double crossed-aldol condensation of a variety of aromatic aldehydes with 1,3-dioxan-5-one in the presence of magnesiumbromide diethyl etherate and diethylamine at room temperature is described. Excellent yields of 4,6-bis(arylmethylidene)dioxan-5-ones are achieved in a facile, one-pot, general procedure. The structure and the Z, Z-configuration of the exocyclic double bonds of the products were determined
