A domino desulfurative coupling–acylation–hydration–Michael addition process for the synthesis of polysubstituted tetrahydro-4H-pyrido[1,2-a]pyrimidines†
Abstract
A novel method for the synthesis of the polysubstituted tetrahydro-4H-pyrido[1,2-a]pyrimidines through a domino desulfurative coupling–acylation–hydration and Michael addition sequence was established.
