This invention relates to a new synthetic process for the manufacture of zidovudine from the starting material D-xylose involving:
i) Conversion of D-xylose to a 2ʹ,3ʹ,5ʹ-protected derivative of 1-(β-D-xylofuranosyl)thymine;
ii) 2ʹ-Deoxygenation of the xylofuranosyl thymine; and
iii) 3ʹ-Azidation of the 2ʹ-deoxy compound.
