Peptide synthesis. Part 2. Procedures for solid-phase synthesis using N α -fluorenylmethoxycarbonylamino-acids on polyamide supports. Synthesis of substance P and of acyl carrier protein 65–74 decapeptide

Use of base-labile Nα-9-fluorenylmethoxycarbonylamino-acids in combination with acid-labile t-butyl or p-alkoxybenzyl side-chain or carboxy-terminal (resin-linkage) protecting groups enables solid-phase peptide synthesis to be carried out under exceptionally mild reaction conditions. The repetitive and vigorous acidic treatments required in conventional synthesis are avoided. High-yield syntheses of a decapeptide and of an undecapeptide amide (Substance P) are described using this new combination of protecting groups on polyamide supports.
