Cu(Otf)2 Catalyzed Regioselective N3-Arylation Of Biginelli 4-Aryl-3,4-Dihydropyrimidin-2(1H)-One Using Symmetrical Diaryliodonium Salt
Keywords:
Aldehyde, β –Ketoester, Urea.Abstract
The Biginelli reaction is a simple one pot three-component condensation of an aldehyde, β-ketoester and urea in presence of a catalytic quantity of acid to produce biologically important 3,4-dihydropyrimidin-2-(1H)-ones (DHPMs) scaffolds.1-4 However, the classical Biginelli reaction fails to produce N3-arylated dihydropyrimidones using N-arylurea as one of the reacting component. In this case, N1-arylated DHPMs are obtained as the sole product.12 Therefore; there is a necessity to perform N3-arylation of DHPMs to furnish decorated cyclic urea analogues.
