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
