Access from EThOS:
An elegant synthesis of hitherto inaccessible naphthopyrans bearing one or more strongly electron withdrawing sulfone functions was accomplished. Key to the success of this approach was the development of the deactivating sulfone unit through the oxidation of a thioether moiety post to the Claisen propargyl ether rearrangement to form the naphthopyran.
