  An improved direct synthetic approach to anhydronucleosides

  摘要：

  The synthesis of anhydrothioglycosyls has been improved by studying the reaction under a variety of reaction conditions including gas phase pyrolysis, heating in a solvent of high boiling point, in the presence of different bases including triethylamine, DABCO, and DBU, and in a microwave reactor.
