Dehydrosulfurative arylation with concomitant oxidative dehydrogenation for rapid access to pyrimidine derivatives

Abstract

This report describes a cascade reaction method for the synthesis of 2-arylpyrimidine derivatives via dehydrosulfurative carbon-carbon cross-coupling and concomitant oxidative dehydrogenation under a Pd/Cu catalytic system. It provides rapid and general access to a diverse range of 2-arylpyrimidines in a single step from a wide range of 3,4-dihydropyrimidin-1H-2-thiones (DHPMs) and arylboronic acids.
