dehydrosulfurative carbon–oxygen cross-coupling reaction with boric ester and six-membered cyclic thiourea for single-step production of densely substituted 2-alkoxypyrimidines incorporated in a privileged scaffold is described. This is the first demonstration of boric ester acting as an alkoxy donor in a metal-catalyzed coupling reaction to produce ether. The reaction method offers a shortcut for producing
