ABSTRACT
Bicyclic acetal was known as a versatile reagent for the structural transformation reactions. Bicyclic acetal was functionalized to the acetal-lactol and halo-lactol, and applied for the new rearrangement reactions. The structural identification and rearrangement mechanism were discussed herein.
