title: Mn(III)-catalyzed radical reactions of 1,3-dicarbonyl compounds and cyclopropanols with vinyl azides for divergent synthesis of azaheterocycles.
abstract: 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.
