The first stereoselective rhodium-catalyzed intermolecular aziridination and C–H amination of alkenes to produce chiral carbamate-protected aziridines and allylic amines is described. Good yields and diastereoselectivities were achieved using a readily available chiral N-tosyloxycarbamate and stoichiometric amount of the alkene substrate. Furthermore the protecting group is easy to cleave under mild
描述了第一次立体选择性铑催化的分子间叠氮和烯烃的CH胺化反应,以产生手性氨基甲酸酯保护的氮丙啶和烯丙基胺。使用容易获得的手性N-甲苯磺酰氧基氨基甲酸酯和化学计算量的烯烃底物可获得良好的收率和非对映选择性。此外,保护基在温和的反应条件下易于裂解。
