Hi everyone 

I am having some problems determining the choice of this reaction. I have the reaction posted below, and there are also 4 choices. I am thinking that the cyclic group would attach to both the O on the anomeric carbon, as well as to the O on the highest stereogenic centre which determines D/L structure.

So I am thinking that there are no cyclic structures adding on to the given structure, but none of the choices fit with my reasoning...

The correct answer is choice 2. In the absence of cyclohexanol the sugar can ring close to give the hemiacetal. If you add an alcohol plus acid to a hemiacetal you get an acetal. Look up hemiacetal and acetal in your text and you'll see what I mean.
