A General Procedure for Synthesis ofNG-Alkyl, andNG-Aryl-L-Arginines as Potential Nitric Oxide Synthase inhibitors
摘要:
AbstractA general procedure for the synthesis of NG‐alkyl, and NG‐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 NG‐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%.
