摘要

Abstract A new method for the solid??phase synthesis of N??aryl??N′??carboalkoxy guanidines is described. Aromatic amines were reacted with Fmoc??isothiocyanate to provide Fmoc?? thioureas, which were coupled with Rink amide resin to provide the corresponding resin?? bound Fmoc??guanidines. Subsequent Mitsunobu alkylation with a variety of alcohols delivered N??aryl??N′ carboalkoxy guanidines in good to high purity after resin cleavage.
