An Intramolecular PIFA-Mediated Metal-Free Allylic Oxycarbonylation Reaction and Its Application to the Preparation of Furopyrimidinones
摘要:
The preparation of a series of furo[3,4-d]pyrimidinones by an unprecedented PIFA-mediated intramolecular allylic oxycarbonylation reaction developed on 5-carbamoyl-substituted Biginelli adducts is presented The construction of the fused lactone by a metal-free C-H activation process, without the need of an additional functionalization step, is featured in the present work
