  2. 1. Lewis Acid Mediated [2,3]-Sigmatropic Rearrangement of Allylic Ammonium Ylides

    Author : Jan Blid; KTH; []
    Keywords : Sigmatropic rearrangement; Lewis acid; Ammonium ylide; NMR spectroscopy; Density functional calculations;

    Abstract : This thesis describes a Lewis acid mediated[2,3]-sigmatropic rearrangement of various allylic ammoniumylides. Several Lewis acids are investigated and BBr3 and BF3are established to be the Lewis acids providing the highestconversion of the starting allylic amines. READ MORE

  4. 2. Asymmetric [2,3]-Sigmatropic Rearrangement of Allylic Ammonium Ylides

    Author : Jan Blid; Peter Somfai; James C. Anderson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric; [2; 3]-sigmatropic rearrangement; allylic amine; ammonium ylide; Lewis acid; enantioselective; boron; phosphazene base; NMR spectroscopy; DFT-calculations; Organic chemistry; Organisk kemi;

    Abstract : The thesis describes the realization of an asymmetric [2,3]-sigmatropic rearrangement of achiral allylic amines. It is divided into two parts; the first part deals with the development of a Lewis acid-mediated [2,3]-sigmatropic rearrangement and the second the asymmetric version thereof. READ MORE
