Abstract

Abstract A general procedure for the synthesis of N G-alkyl, and N G-aryl-L-arginines with relatively high overall yield is reported. The key step involved the coupling of protected L- ornithine 4 with isothiourea 7 to give the fully protected N G-aryl-L-arginine derivative 8. Subsequent deprotection of 8 in acidic condition provided the final target compound 9 with an overall yield of more than 80%.
