Sažetak

The fully protected octapeptide VII with the amino acid sequence
of the human insulin B23-ao chain has been synthesized by
the condensation of the N-terminal tripeptide I and C-terminal
pentapeptide VI fragments which were prepared stepwise. The
N-terminal group of VII was protected by the benzyloxycarbonyl
group, whereas all the other functions of VII were blocked by the
use of the tert-butyloxycarbonyl and tert-butyl group, resp~ctively.
Catalytic hydrogenation of VII gave the partially protected octapeptide
VIII.
