Webb5 sep. 2003 · Benzoylated D-glucose, D-galactose and L-quinovose DISAL glycosyl donors were synthesized in high yields and used under mild conditions to glycosylate methyl saphenate and 2-hydroxyphenazine. Webb3 indicated only 16 carbon signals, one of them at δ 167 was probably due to an ester carbonyl. The 1H and 13C NMR data and the molecular formula pointed therefore to a symmetrical dimer. A search in AntiBase [2] led to phenazostatin B (1a) [3][4, 5] which on direct comparison indeed showed very similar yet not identical NMR data (Tab. 1) and …
