azidoformates to construct aziridine/oxazolidinone-fused bicyclic structures. The Co(II) complex of D2-symmetric chiral amidoporphyrin 3,5-DitBu-QingPhyrin has been identified as an effective metalloradical catalyst for the intramolecular radical aziridination of this type of carbonyl azides, allowing for high-yielding formation of synthetically useful chiral [3.1.0]-bicyclic aziridines with high diastereo-
基于钴(II)的金属催化已成功地用于烯丙基叠氮基甲酸酯的自由基双环化,以构建氮丙啶/恶唑烷酮融合的双环结构。D 2对称的手性氨基卟啉3,5-Di t Bu-QingPhyrin的Co(II)配合物已被鉴定为这种羰基叠氮化物分子内自由基叠氮化的有效金属铁催化剂,可合成高产具有高非对映体和对映体选择性的有用的手性[3.1.0]-双环氮丙啶。
