Abstract

l-(-halo-2,2-difiuor-2-deoksy-D-ribofuranosederivat av formel (I) som har en 3-hydroksygruppe beskyttet med en bifenylkarbonylgruppe, er et fast materiale som lett kan renses ved en enkel prosedyre slik som omkrys-tallisering, og derfor kan det fordelaktig anvendes som et mellomprodukt ved fremstilling av gemcita-bin i stor skala. Enn videre kan l-(-halo-2,2-difluor-2-deoksy-D-ribofuranosederivatet av formel (I) fremstilles med høy stereoselektivitet under anvendelse av forbindelsen av formel (V) som mellomprodukt.
