On August 15, 1990, El-Sokkary, Ramadan I.; Silwanis, Basim Azmy; Nashed, Mina A.; Paulsen, Hans published an article.Electric Literature of 130539-43-4 The title of the article was Standardized intermediates for oligosaccharide synthesis: convenient preparation of 2-amino-2-deoxy-D-glucose derivatives and their conversion into the D-galactose analogs. And the article contained the following:

Treating tetraacetate I (R = Ac, NPhth = phthalimido) with allyl alc. in CH2Cl2 containing FeCl3 gave I (R = CH2:CHCH2O) which was deacetylated by NaOMe-MeOH followed by benzoylation with BzCl to give 95.8% phthalimido derivative II. The latter was treated with (CF3SO2)2O in CH2Cl2 to give an intermediate 4-triflate which was converted by NaNO2-DMF to 86% galactopyranoside III, a useful glycosyl donor for oligosaccharide synthesis. The experimental process involved the reaction of Ethyl 2-deoxy-2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)-1-thio-beta-D-glucopyranoside(cas: 130539-43-4).Electric Literature of 130539-43-4
