Abstract: An artificial receptor 1 for aromatic amino acids was prepared from a chiralbicycllc guanidine salt 2 by means of a new procedures.The deprotecting silylethers 2 and 4were selectively achieved in solutions of CH3COOH-THF-H2Oand HF-Pyridine respectively.Thus the receptor 1 was readily obtained upon reaction of the monosubstituted naphthoylester 5 with bromoacetic acid and then mono-azacrown ether.The total yield in five steps was40.5%.
