A disaccharide analogue (A4 = 13c) of moenomycin A lacking the OH group in the 4-position of the uronic acid moiety has been synthesized using the Saito deoxygenation reaction as key step. 13c does not inhibit the transglycosylase (PBP 1b), a key enzyme in the biosynthesis of bacterial peptidoglycan. The result demonstrates the importance of this OH group for the binding of disaccharide moenomycin analogues to the enzyme. (C) 1999 Elsevier Science Ltd. All rights reserved.
