%X Syntheses are described of two pentapeptide derivatives with the A5-9 and A17-21 sequences, respectively, of ovine insulin, and of a protected tetrapeptide with a modified A1-4 sequence. Preparation of the three compounds involved the use of the 2,4,6-trimethylbenzyl carboxyl-protecting group in conjunction with the o-nitrophenylsulphenyl and benzyloxycarbonyl amino-protecting groups.
