Vedejs, Edwin,Sano, Hiroshi
, p. 3261 - 3264 (2010/11/30)
Electron-rich alkenes are converted into N-methoxyaziridines by treatment with HN(OCH3)2 and trimethylsilyl triflate.Reduction with Li/ammonia affords the N-H aziridines. Key words: Aziridine; N-methoxyaziridine; N-methoxycaprolactam; dimethoxyamine; nitrenium ion
