Stereocontrolled Synthesis of a Polyether Fragment

A sequence utilizing selenolactonization of olefinic acid 4, Ireland-Claisen rearrangement of ketal ester 9, iodolactonization / epoxidation of olefinic acid 10, and regioselective hydrolysis of epoxide 15b is described for the stereocontrolled conversion of meso-2,4-dimethylglutaric anhydride to racemic tetrahydropyran lactone 1.
