Abstract
2',3'-Dideoxy-6',6'-difluorouracils, a novel series of gem-difluoromethylenated carbocyclic nucleosides, were synthesized from (Z)-but-2-ene-1,4-diol in 14 steps. A notable step was the construction of the carbocyclic ring via ring-closing metathesis and the incorporation of gem-difluoromethylene group by way of silicon-induced Reformatskii-Claisen reaction of chlorodifluoroacetic ester 3.
