with complete retention of chirality as evidenced by NMR and HPLC analysis. Arginine LL-dipeptides 15a-d were synthesized by extension at the C-terminus of arginine in isolated yield of 66-80%, using benzotriazole activated arginine L-(omega)NO2-Arg-Bt, 13. Our methodology has also been used to synthesize the protected RGD peptide (Cbz(alpha)-L-(omega)NO2-Arg-Gly-L-Asp-(OH)2) 21.
