A short Synthesis Of L-aminohomohistidine (L-Ahh) is described, which starts from readily available delta-hydroxy-L-lysine. The embedding of the basic guanidino Moiety in the aromatic imidazole lowers the basicity of the side chain to a pK(a), of 8.3. It is proposed that L-Ahh may be employed as an arginine-mimetic in medicinal chemistry. (C) 2004 Elsevier Ltd. All rights reserved.
