Abstract

Novel three-component cyclocondensation reaction by use of a bisÃ?Â?reagent: New synthesis of diethyl 4,4-(1,4-phenylene) bis(6- methyl-2-oxo(thioxo)-1,2,3,6-tetrahydropyrimidine-5-carboxylates (biginelli reaction)

The one-pot, three-component (Biginelli reaction) cyclocondensation reaction of ethyl acetoacetate, terephthalaldehyde and urea in the ratio of 2: 1: 2 in absolute ethanol solvent in the presence of dodecyl benzene sulfonic acid (DBSA) as catalyst leads to the formation of the title compound in a good yield.
