Metalloporphyrin-catalysed rearrangement of oxaziridines: an efficient and regioselective synthesis of lactams using ring-enlargement of N-phenyl-spirooxaziridines
Metalloporphyrin-catalysed rearrangement of oxaziridines: an efficient and regioselective synthesis of lactams using ring-enlargement of N-phenyl-spirooxaziridines
Manganese(III) tetraphenylporphyrin, Mn(tpp)Cl, is a new and specific catalyst for stereo- and regio-selective rearrangement of N-phenyl-spirooxaziridines into lactams.
