ChemInform Abstract
Electrolysis of silylated pyrimidines (II) with protected arylthioribose (I) in the presence of a catalytic amount of NBS or Br2 as mediator gives the corresponding nucleosides in good yields. The stereoselectivity of this glycosylation is similar to that of chemical glycosylation using a stoichiometric amount of NBS.
