Mn(iii)-Catalyzed Radical Reactions of 1,3-Dicarbonyl Compounds and Cyclopropanols with Vinyl Azides for Divergent Synthesis of Azaheterocycles

Mn(iii)-catalyzed formal [3+2]- and [3+3]-annulations have been developed using readily available vinyl azides with 1,3-dicarbonyl compounds and cyclopropanols. Vinyl azides were successfully applied as a three-atom unit including one nitrogen to prepare various azaheterocycles via Mn(iii)-catalyzed radical reactions
