We describe the synthesis of the unusual bicyclic sugar bradyrhizose in 14 steps and a 6% overall yield fromd-glucose. The synthesis involves the elaboration of a trans-fused carbocyclic ring onto the preexisting glucopyranose framework followed by adjustment of the oxidation levels. Key steps include radical extension of the glucopyranose side chain, ring closing metathesis, allylic oxidation, Luche
