Synthesis of fused pyran-carbahexopyranoses as glycosidase inhibitors

Synthesis of polyhydroxylated oxabicyclo[4,4,0]decanes, which constitute a new family of annulated carbasugars, has been accomplished in a stereoselective manner by employing readily available 1,2-anhydro-3,4,6-tri-O-benzyl-α-d-glycopyranoses.
