  1. 1. Synthesis and Applications of P-chirogenic Phosphine Boranes

    Author : Magnus Johansson; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytisine; gold I catalysis lipase; P-chirogenic; desymmetrization; phosphine; enantioselective cyclopropanation. enantioselective deprotonation; chirality; asymmetric synthesis; borane;

    Abstract : AbstractThis thesis reports the independent synthesis of both enantiomers of P-chirogenic phosphine ligands and the building blocks thereof, which are suitable for parallel synthesis efforts and for the generation of more diverse libraries of P-chirogenic compound. The use of P-chirogenic phosphine boranes in transition metal-catalyzed reactions, such as palladium-catalyzed allylic alkylation and amination, is also described. READ MORE

  3. 3. Synthesis and Applications of P-Chirogenic and Axially Chiral P,N-Phosphines as Ligands and Organocatalyst

    Author : Kristian Andersson; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phosphoramidite; organocatalysis; aminophosphine; Nicholas reaction; asymmetric synthesis; phosphine; asymmetric hydrogenation; modular synthesis; P-chirogenic;

    Abstract : This thesis deals with the enantioselective synthesis of chiral mixed phosphorous/nitrogen compounds and some of their applications in asymmetric synthesis. For the most part, the compounds are P-chirogenic, with the chirality centered on the phosphorous atom. The last part of the thesis deals with axially chiral phosphoramidites. READ MORE
