The Lewis acid catalysed addition of 1-trimethylsilyl nitropropanate to imines.
850 - 852.
The scandium triflate catalysed addition of I-trimethylsilyl nitropropanate to aryl and alkyl imines is described. The use of N-(4-methoxyphenyl)imines gave superior yields and/or diastereoselectivities of beta-nitro amines in most cases examined. The product beta-nitro amines can be readily manipulated to 1,2-diamines by samarium diiodide reduction. formation of the cyclic urea and removal of the l-methoxyphenyl group with eerie ammonium nitrate.
