A practical strategy for solid phase synthesis of peptide aldehydes is
described. An olefin linker is constructed using Wittig chemistry, af
ter peptide synthesis ozonolylic treatment of the linker and subsequen
t workup with dimethyl sulphide results in facile isolation of peptide
aldehydes. The principle is demonstrated by synthesis of a 3x3x3 arra
y of 27 tripeptide aldehydes. (C) 1998 Elsevier Science Ltd. All right
