A NEW SYNTHESIS OF 2,3,4,6-TETRA-O-BENZYL-D-GLUCOPYRANOSYLIDENE ACETALS, USING TRIMETHYLSILYL TRIFLUOROMETHANESULFONATE AS THE CATALYST

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

A FACILE SYNTHESIS OF 2,3,4,6-TETRA-O-BENZYL-D-GLUCOPYRANOSYLIDENE ACETALS USING TRIMETHYLSILYL TRIFLUOROMETHANESULFONATE CATALYST

The application of acetalization of aldehydes and ketones by alkoxysilanes in the presence of trimethylsilyl trifluoromethanesulfonate catalyst to lactones and di-O-trimethylsilyl-α-diols gave readily the corresponding spiro ortho esters.

Synthesis and Stereochemistry of 2,3,4,6-Tetra-O-benzyl-D-glucopyranosylidene Acetals of α-Diols and Monosaccharides

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.
