Abstract

A collective total synthesis of eight diastereoisomers associated with NMR analysis leads to a full stereochemistry assignment of the structurally unique nucleoside antibiotic A-94964, which features an octuronic acid uridine core decorated with an α-D-mannopyranosyl residue and an α-D-N-acylglucosaminopyranosyl residue via a phosphodiester bridge.
