WebNov 20, 2015 · The choice of guanidine precursor usually has depended upon the reactivity of the amine involved; in the case of anilines, Lewis acid-promoted reactions have been the most successful, whilst for aliphatic amines, there is a much wider range of guanidine precursors available due to their greater nucleophilicity. WebBecause the guanidino group contains two reactive nitrogens, rather than only one as in the lysine side chain, it shows a more diverse chemistry. Reaction with dicarbonyl compounds readily yields five membered, imidazole-type, rings systems, with various substitutions and regio-isomers.
