Synthesis, conformational and configurational studies of some new acetylated glycosides of 2-thio-3-aryl-4(3H)-quinazolinones, their thiono and 3,1-benzothiazin-2,4-dithione

A series of some new acetylated S-glycosides of 2-thioxoquinazolin-4- ones, their thiono analogues and 3,1-benzothazin-2,4-dithione derivatives, including a D-glucose and a D-galactose derivatives and a D-xylose, and an L- arabinose derivatives have been synthesized. The conformation and configuration of these carbohydrate derivatives were determined by analysing their 1H and 13C NMR chemical shifts and coupling constants. The biological activity of these compounds has been studied.
