  2. 21. Asymmetric 1,3-Dipolar Cycloaddition Reactions of Azomethine Ylides, Thiocarbonyl Ylides, and Nitrones

    Author : Staffan Karlsson; KTH; []
    Keywords : ;

    Abstract : This thesis describes the development of methods for thepreparation of chiral non-racemic substituted pyrrolidines,tetrahydrothiophenes, and isoxazolidines. This has beenaccomplished by using asymmetric intermolecular 1,3-dipolarcycloaddition reactions of azomethine ylides, thiocarbonylylides and nitrones, respectively, with variousdipolarophiles.
