    Abstract : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

  4. 2. A Regio- and Stereodivergent Route to All Isomers of vic-Amino Alcohols

    Author : Berit Olofsson; KTH; []
    Keywords : amino alcohols; vinylepoxides; vinylaziridines; oxazolines; oxazolidinones; ring-opening; regioselective; diastereoselective; sphingosine; configuration; NMR spectroscopy;

    Abstract : The first part of this thesis describes a synthetic strategythat provides all eight possible isomers of a given vic-aminoalcohol starting from vinylepoxides. The value of a generalroute is evident, as several isomers are needed ininvestigations of structure-activity relationships forpharmacologically active derivatives, and for optimizing theperformance of chiral ligands containing the amino alcoholmoiety.
