Abstract

An efficient and highly convergent route to dihydropyrimidinones (DHPMs) has been developed by one-pot three-component oxidative cyclocondensation of a variety of alcohols, β-ketoesters/β-oxodithioester and urea in the presence of T3P®/DMSO. This new approach consistently has the advantage of tandem and good yields (65–88%).
