A new and convenient approach for the synthesis of rffio- and 2′-deoxyrffio-p-l-furanonucleosides starting from β-l-xylofuranonucleosides

Boudou

, p. 607 - 609 (2007/10/03)

Ribo- and 2′-deoxyribo-β-L-ruranosyladenine have been synthesized. Although these compounds have been already reported in the literature, it seemed to us that a more convenient approach for their synthesis deserved to be developed. Intramolecular substitution as well as Mitsunobu reaction were used to invert the configuration of carbon 3′ of starting β-L-xylofuranosyl intermediates. Copyright
