K. Teng et al., UTILITY OF OYLTETRAHYDROFURAN-2'-YL)-3-BENZYLOXYMETHYLTHYMINE FOR THESYNTHESIS OF 5'-MODIFIED FURANOID NUCLEOSIDE ANALOGS, Synlett, (4), 1996, pp. 346-348
A series of 5'-modified furanoid nucleosides have been prepared in ver
y good yields by the reaction of oxytetrahydrofuran-2'-yl)-3-benzyloxy
methylthymine (1) with alcohols, a sulfide, and TMS-azide in the prese
nce of TMSOTf. The reactions proceed in a stereospecific manner to pro
vide only beta-glycosylation products.
