  2. 1. Natural Product Synthesis and Development of Novel Reaction Methodology

    Author : Jakob Danielsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; perophoramidine; communesin; quaternary stereocenter; Diels-Alder; 1; 2-asymmetric induction; polar Felkin-Anh; Cornforth-Evans; Mukaiyama aldol; 3-dipolar cycloaddition; azomethine ylide; 2-amino alcohol; anti-α-amino-β-hydroxy ester;

    Abstract : This thesis deals with the development of new reaction methodology for stereoselective synthesis, as well as total synthesis of natural products and investigations of the stereochemical outcome in the Mukaiyama aldol reaction. Chapter 2 describes efforts made towards the total synthesis of the oxindole natural products perophoramidine and the communesin. READ MORE

  4. 2. Stereoselective Nucleophilic Additions to Aldehydes and Synthesis of α-Amino-β- Hydroxy-Esters

    Author : Jakob Danielsson; Peter Somfai; Hans Adolfsson; Tobias Rein; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asymmetric induction; stereochemical models; Mukaiyama; polar Felkin-Anh; Cornforth-Evans; 1; 3-dipole; aziridine; cycloaddition; amino alcohol; carbonylation; Heck reaction; quaternary stereocenter;

    Abstract : This thesis deals with the development of new reaction methodology as well as stereochemical investigations. The first part concerns the investigation of 1,2- and merged 1,2- and 1,3- asymmetric induction in Mukaiyama aldol additions to α-heteroatom and α,β- heteroatom substituted aldehydes respectively.
