S. Peluso et B. Imperiali, Asparagine surrogates for the assembly of N-linked glycopeptide mimetics by chemoselective ligation, TETRAHEDR L, 42(11), 2001, pp. 2085-2087
Alanine-beta -hydroxylamine (A betax) and alanine-beta -hydrazide (A betaz)
have been developed as asparagine surrogates for the assembly of N-linked
glycopeptide mimetics by chemoselective ligation. The utility of these resi
dues is illustrated with the synthesis of the oligosaccharyl transferase su
bstrate mimetics 1 and 2, and conjugation thereof with GlcNAc to obtain the
N-glycopeptide mimetics 3 and 4. (C) 2001 Elsevier Science Ltd. All rights
