Herein, we report that iodine-catalyzed guanylation of primary amines can be accomplished with N,N'-di-Boc-thiourea and TBHP to afford the corresponding guanidines in 40-99% yields. Oxidation of the HI byproduct by TBHP eliminates the need for an extra base to prevent the protonation of substrates and makes the reaction especially useful for both electronically and sterically deactivated primary anilines

A novel and efficient synthetic procedure for converting a diverse set of amines to N,N′ -di-Boc-protected guanidines is described. The methodology comprises the use of cyanuricchloride (TCT) as activating reagent for di-Boc-thiourea. The employ of inexpensive TCT instead of classical HgCl 2 eliminates the environmental hazard of heavy-metal waste without appreciable loss of yield or reactivity. This

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.
