Abstract
A novel and efficient two-step synthesis of 5-aroyl-3,4-dihydropyrimidin-2-ones is reported. These privileged ketone structures are readily generated by microwave-assisted Liebeskind-Srogl-type coupling of boronic acids with the corresponding pyrimidone thiol esters. The thiol esters themselves are easily prepared using Biginelli multicomponent chemistry.
