Samarium(II) iodide mediated intramolecular homelytic substitution at selenium: Preparation of 5-seleno-D-pentopyranose sugars from common pentose starting materials

Treatment of 2,3,4-tri-O-benzyl-5-benzylseleno-5-deoxyribose (9) with samarium(II) iodide in THF affords 2,3,4-tri-O-benzyl-5-deoxy-5-seleno-D- ribopyranose (10) in 50% isolated yield in a process most likely involving intramolecular homolytic substitutio

Exploratory experiments with aryl telluride carbohydrates. Synthesis of carbocycles using intramolecular radical cyclization

The preparation of cyclohexanoids and cyclopentanoids, potential precursors of biologically interesting molecules is described. The key step of the synthesis is an exo cyclization of 5-hexenyl or 6-heptenyl radicals. The radical, generated by radical exchange from carbohydrate anisyl tellurides (D-galactose or D-arabinose) cyclized into polyhydroxylated cyclohexane or cyclopentane derivatives.
