A general method has been developed for the stereoselective construction of 2,6-disubstituted dihydropyrans based on the Lewisacid-catalyzed intramolecular reactions of oxocarbenium ions with vinylstannanes. This novel methodology was applied to the enantioselective total synthesis of (−)-centrolobine.
