  • Title: Stereoselective syntheses of enantiomerically pure 2,5-disubstituted dihydropyrans based on olefin metathesis.
    Author: Schmidt B, Nave S.
    Journal: J Org Chem; 2006 Sep 15; 71(19):7364-9. PubMed ID: 16958531.
    Abstract:
    A short synthesis of 2,5-disubstituted dihydropyrans starting from d-mannitol as a chiral building block is described. Our synthetic approach combines ruthenium-catalyzed ring closing olefin metathesis and palladium-catalyzed nucleophilic substitution.
