Base-lable 2-(4-nitrophenylsulfonyl)ethoxycarbonyl (Nsc) group is proposed for a temporary α-amino protection in the solid phase peptide synthesis. Nsc-Group is cleaved by organic bases in aprotic solvents under mild conditions similar to that used for Fmoc-group. Several Nα-Nsc amino acids are prepared and used in the solid phase synthesis of the fragment 307–318 of S-protein from bovine eye retina
为了在固相肽合成中的临时α-氨基保护,提出了碱可支持的2-(4-硝基苯基磺酰基)乙氧基羰基(Nsc)基团。在与Fmoc-group相似的温和条件下,Nsc-Group在非质子传递溶剂中被有机碱裂解。制备了几种Nα-Nsc氨基酸,并将其用于固相合成牛眼视网膜S蛋白的307-318片段。
