A new strategy for the synthesis of peptide aldehydes on solid support
is presented. Reaction of a N-protected alpha-amino aldehyde with MBH
A-supported Wittig ou Wittig-Homer reagent yielded resin-linked alpha-
beta-unsaturated delta-amino derivative. After elongation of the pepti
de chain, ozonolysis produced fairly pure C-terminal peptide aldehydes
in good yield. (C) 1998 Elsevier Science Ltd. All rights reserved.
