β¦ Synopsis
N-[9-(hydroxymethyl)
.2.tluorenyl] succinamic acid may be used as an anchoring linkage for the preparation of protected peptide segments in combination with Boc/Bzl' protection scheme. The new handle proved to be stable to the usual conditions of solid-phase peptide synthesis and gave the protected peptide in high yields and purities by neatment with piperidine or morpholine.

High yklds for the cleavage reaction of Fmoc-protected peptide segments fmn an allylic handle may be obtained using tributyltin hydride in the jmsence of (ph3P)PdQ in a 1:l mixture of DMF/DCM. Altematively tbe cleavage reacdon may be carried out using NMA as nuclecpbile in a 2:2:1 mixture of DMSOfl'
A new hydroxy-protecting group for Ser, cyclohexyl, has been developed, and its application to the solid-phase peptide synthesis has been demonstrated successfully in combination with NΒ°t-Boc protection and the Merrifield resin support.
