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

Preparation of 5-selenopentopyranose sugars from pentose starting materials by Samarium(II) iodide or (phenylseleno)formate mediated ring closures

2,3,4-Tri-O-benzyl-1,5-dideoxy-5-seleno-D-pentopyranose sugars (16, 23,24) are readily prepared by thermolysis of 2,3,4-tri-O-benzyl-5- benzylseleno-D-ribit-1-yl formate, 2,3,4-tri-O-benzyl-5-benzylseleno-D-xylit- 1-yl formate and 2,3,4-tri-O-benzyl-5-ben
