The recently described FMOC/4-AMP technique for rapid continuous solution synthesis of peptides involving coupling by crystalline FMOC amino acid chlorides and deblocking via 4- (aminomethy1) piperidine (4-AMP) has been extended to the synthesis of a varied number of tachykinin peptides. Previously only the simple pentapeptide leucine enkephalin had been synthesized by this procedure. Continuous syntheses of peptides up to the ...
