[Synthesis of human [11-leucine]minigastrin I.--I. Preparation of the fully protected tridecapeptide amide (author's transl)].

The synthesis of the tridecapeptide amide corresponding to and 11-leucine analog of human minigastrin I is decribed. The fully protected peptide derivative was obtained by assembly of three suitably protected fragments corresponding to the sequences 1-6, 7-9 and 10-13 by the carbodiimide/N-hydroxysuccinimide method.
