Abstract: In this paper, we developed a rhodium-catalyzed annulation of vinylene carbonate with amidines, leading to 4-methylquinazolines with moderate to excellent yields. This procedure proceeded by sequential ortho-acylation and annulation, where vinylene carbonate served as the… read more here.
