Summary
The solid-phase synthesis of an octacosapeptide amide corresponding to the amino acid sequence of porcine vasoactive intestinal peptide (VIP) is described. No final treatment with strong, anhydrous acid was employed, since the use of base-labile 9-fluorenylmethyloxycarbonyl amino acids bearing tert-butyl based side chain protection enabled the peptide chain assembly to be performed on p-benzyloxybenzyl amine resin, which was cleaved from the whole peptide amide at the end of the synthesis by diluted trifluoroacetic acid.
