Application

Methyl 2,3-anhydro-4,6-O-benzylidene-α-D-allopyranoside has been used in a study to assess benzylidene acetal ring-opening of a 2-cyano-2-deoxypyranoside derivative. It has also been used in a study to describe new simple routes to the title epoxide using carbonate esters.

The oxirane ring-opening of an anhydro sugar with diethylaluminum cyanide (Et(2)AlCN) is a direct approach for obtaining a cyano derivative. Methyl 2,3-anhydro-4,6-O-benzylidene-alpha-D-allopyranoside showed anomalous chemical behavior when treated with Et(2)AlCN. The reaction afforded the corresponding beta-cyanohydrin as the minor component
