A green and highlyefficientone-potsynthesis of 16 1,3,4,5-tetrasubstituted 1,2,3,6-tetrahydropyrimidines, four of which are new, using a three-component reaction involving an aniline, formaldehyde and a dialkyl acetylenedicarboxylate in aqueous media at room temperature catalysed by nano-MoO3 has been achieved.

It is the first report of 1,3,4,5-tetrasubstituted 1,2,3,6-tetrahydropyrimidines derivatives, catalyzed by ZrOCl2. The mild reaction conditions, excellent yields in shorter reaction time and evasion of cumbersome workup procedures make this process economically lucrative for industrial application. The novelty and highlight of the present method is the promising antibacterial and antifungal activity shown by compounds (4a, 4b, 4e, 4f, 4h and 4l) compared to standard. (C) 2013 Elsevier Ltd.
