The title compounds were synthesized by condensation of 2,3,4,6-tetra-O-benzyl-D-glucono-1,5-lactone with bis-O-(trimethylsilyl)-1,2-diols in the presence of trimethylsilyl trifluoromethanesulfonate as the catalyst.Application to cis- and trans-1,2-diols

The title compounds were synthesized by addition of 2,3,4,6-tetra-O-benzyl-D-glucono-1,5-lactone to epoxides and by direct dehydration between the lactone and diols in the presence of concentrated sulfuric acid as a catalyst.Stereochemistry of these spiro cyclic acetals was discussed.
