T. Breining et al., 1',2',6'-THIADIAZINE 1',1'-DIOXIDE AND IMIDAZO [4',5'-C] [1',2',6']-THIADIAZINE 2',2'-DIOXODE-1,3-OXATHIOLANE NUCLEOSIDE ANALOGS - SYNTHESIS AND ANTI-HIV-1 ACTIVITY, Heterocycles, 41(1), 1995, pp. 87-94
A series of 1,3-oxathiolanes containing the 1,2,6-thiadiazine dioxide
moieties were synthesized by various coupling conditions of the oxathi
olane sugar (3) and silylated 1,2,6-thiadiazine dioxides (4-7) as base
s. The compounds were evaluated for their potential anti-HIV activitie
s in MT-4 cells and were found to lack activity at 100 mu g/ml.
