stereoselective methodology has been developed for the construction of cis-fused perhydrofuro[2,3-b]furans, via 3-C-branched glycal derivatives, involving Claisen rearrangement of sugar-derived allyl vinyl ethers, followed by a one-pot ozonolysis and acid-mediated acetalization. The methodology was used for the stereoselective synthesis of the P2 ligand in the recently FDA approved HIV protease inhibitor darunavir
