R. Herranz et al., SOLID-PHASE SYNTHESIS OF PSI[CH(CN)NH] PSEUDOPEPTIDES - APPLICATION TO THE SYNTHESIS OF ANALOGS OF NEUROTENSIN [NT(8-13)], Tetrahedron letters, 34(51), 1993, pp. 8357-8360
The introduction of the cyanomethyleneamino [CH(CN)NH] group, a new ty
pe of peptide bond surrogate, under solid phase peptide synthesis cond
itions has been studied using both Boc and Fmoc strategies. The pseudo
hexapeptides H-Arg-Arg-Pro-Tyr Psi[CH(CN)NH]Ile-Leu-OH (1) and H-Arg-A
rg-Pro-Tyr-Ile Psi[CH(CN)NH]Leu-OH (2), analogues of the C-terminal he
xapeptide of neurotensin [NT(8-13)], were successfully obtained via Fm
oc synthesis.
