This paper describes the racemic and stereoselective synthetic route for a novel6′(α)-hydroxy-carbovir from a simple acyclic precursor, Solketal. The relative stereochemistry of the target nucleosides was successfully controlled by a sequential stereoselective glycolate Claisen rearrangement followed by a ring-closing metathesis (RCM). Adenine and cytosine were coupled using a Pd(0) catalyzed allylic
