✦ Synopsis

Two series of peptides with hydrophobic side chains, Nps-(L-Leu-L-Leu-L-Ala),OEt and Nps-(L-Met-L-Met-L-Leu),-OEt (n = 1-61. were synthesized by the fragment condensation method using dicyclohexylcarbodiimide in the presence of N-hydroxysuccinimide. The tripeptide fragments were prepared stepwise by dicyclohexylcarbodiimide-mediated reaction of Nps-amino acids, which were synthesized by an improved rapid procedure.
