Dallinger, Doris,Gorobets, Nikolay Yu.,Kappe, C. Oliver
, p. 1205 - 1208 (2003)
(Matrix presented) The solution-phase synthesis of N3-acylated dihydropyrimidines was achieved utilizing microwave flash heating both in the synthesis (acylation) and purification (scavenging) steps. Quenching times for excess anhydrides using polystyrene

One pot condensation of ethylacetoacetate with various para and ortho substituted aldehydes and urea or thiourea by SnCI2.2H20 affords eight different substituted 3,4-dihydropyrimidine ones/ thiones. Further we prepared acetylated 3,
A mild and practical method for the regioselective synthesis of N-acylated 3,4-dihydropyrimidin-2-ones. New acyl transfer reagents
Singh, Kamaljit,Singh, Sukhdeep
