Protecting carbohydrates with ethers, acetals and orthoesters under basic conditions

Chlorinated ethyl and vinyl ethers are introduced at various positions of carbohydrates. Depending on the relative stereochemistry, vinylethers, acetals or orthoesters are formed under basic conditions. The products are stable, but are easily deprotected

SYNTHESIS OF SUBSTITUTED 2,7-DIOXABICYCLOHEPTANES: 1,2-ANHYDRO-3,4,6-TRI-O-BENZYL-AND 1,2-ANHYDRO-3,4,6-TRI-O-(p-BROMOBENZYL)-α-D-GALACTOPYRANOSE

The title compounds were synthesized from D-galactose via 9 steps.For obtaining stable, 1,2-blocked D-galactopyranose ethers, the 1,2-hydroxyl groups were protected with an ethylidene group instead of a 1-ethoxyethylidene group.The key intermediates for t
