摘要
We present a concise, less-toxic and broadly applicable method for coupling weakly nucleophilic amines with N,N'-di-(tert-butoxycarbonyl)thiourea, N-(tert-butxoycarbonyl), N'-alkyl/arylsubstituted-thioureas and N,N'-di-(tert-butoxycarbonyl)imidazolidine-2-thione in the presence of copper(II) chloride. Subsequent removal of Boc protecting groups affords guanidines, di-substituted guanidines and 2-aminoimidazolines in modest to excellent overall yields. (C) 2013 Elsevier Ltd. All rights reserved.
