The synthesis, the antibiotic and the transglycosylase inhibiting properties of a disaccharide analogue of moenomycin A in which the NHAc group of unit E is replaced by a hydroxyl function are described. It can be concluded that this NHAc group is essential for eliciting transglycosylase inhibiting properties, in agreement with a recently established solution structure of moenomycin A.
