C. Mouton et al., SYNTHESIS OF HETERODISACCHARIDE-CONTAINING PEPTIDES, FRAGMENTS OF ACTINOIDIN ANTIBIOTICS, Journal of the Chemical Society. Perkin transactions. I (Print), (13), 1998, pp. 2055-2060
Prototypes corresponding to glycopeptide fragments of actinoidin antib
iotics have been synthesized using an L-acosaminyl-D-glucose-containin
g heterodisaccharide linked to 4-hydroxyphenylglycine as pivotal synth
on. This latter compound has been obtained by coupling of a suitably p
rotected D-glucopyranosyl bromide with the blocked amino acid, followe
d by selective deprotection of the glucopyranosyl moiety at C-2 and su
bsequent stereospecific attachment of the acosaminyl unit.
