bioactive carbovir and abacavir were synthesized. The notable steps were the incorporation of fluoromethylene group by way of silicon-induced Reformatskii–Claisen rearrangement of allyl bromofluoroacetate, the construction of the carbocyclic ring via ring-closing metathesis (RCM) and the introduction of base by Mitsunobu reaction.
