title: Tandem alkylation-Michael addition to vinylogous carbonates for the stereoselective construction of 2,3,3,6-tetrasubstituted tetrahydropyrans.
abstract: A stereoselective method for the synthesis of substituted tetrahydropyran derivatives employing a tandem S(N)2-Michael addition sequence to vinylogous carbonates is developed. The method is extended to the synthesis of bicyclic ether motifs present in polyether ladder toxins.
