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.

D008958 Models, Molecular Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures. Molecular Models,Model, Molecular,Molecular Model
D015224 Dideoxynucleosides Nucleosides that have two hydroxy groups removed from the sugar moiety. The majority of these compounds have broad-spectrum antiretroviral activity due to their action as antimetabolites. The nucleosides are phosphorylated intracellularly to their 5'-triphosphates and act as chain-terminating inhibitors of viral reverse transcription. 2',3'-Dideoxynucleosides,Dideoxyribonucleosides,ddNus,2',3' Dideoxynucleosides
