合成路线1
该中间体在本合成路线中的序号：(X)In an alternative procedure, d-nitroarginine methyl ester (VIII) was condensed with sulfonyl chloride (V) giving sulfonamide (IX). The hydrolysis of the ester group of (IX) with LiOH produced carboxylic acid (X). Conversion of (X) to arginine lactam (XI) was effected by treatment with EDC and HOBt. Subsequent opening of the lactam ring of (XI) with sarcosine tert-butyl ester (XII) in the presence of AlMe3 gave rise to dipeptide (XIII). The tert-butyl ester of (XIII) was then cleaved by treatment with trifluoroacetic acid.
