Methyl and benzyl (ethyl 3,4-di-<i>O</i>-benzyl-2-<i>O</i>-benzoyl-1-thio-β-D-glucopyranosyl)uronate were synthesised from a protected thioglycoside in three steps. A regioselective ring opening of the benzylidene acetal with BH₃^.THF generated C6-OH material, which was subsequently oxidised using biphasic TEMPO/BAIB conditions. The resultant uronic acid was esterified with either a methyl or benzyl moiety. The products were obtained on a multigram scale and fully characterised by ¹H, ¹³C and 2D NMR, alongside MS and IR analysis.
