That makes sense. I'm going to use MOM to protect the hydroxyl groups first then try to open the ring. Am I now able to protonate the oxygen in the ring and remove it as water?

Anyone?

I'm looking to synthesize the product here using the starting material (glucose?) shown below. I'm able to use any reagent but I just can't figure out the steps to do so. Should I open the ring first? Substitute the substituents or . . I'm really stumped here. Any help is appreciated!
