Phenylseleno sugars

Although phenylseleno sugars have been most frequently used as radical precursors, their preparation requires the use of odorous phenylselenol. Furthermore, formation of the anomeric radical usually requires BujSnH, which is also unpleasant to work with. An...

Radicals generated thermally with photochemical AIBN initiation from sugars containing halogen, phenylthio, phenylseleno, thiono-carbonate, or xanthate substituents can react with allyl- or methallyl-tributylstannane, leading to extended chain compounds, branched chain compounds and allyl C-glycosldes (e g.
