  1. 6. MECHANISTIC INVESTIGATIONS OF TRANSITION METAL CATALYZED REACTIONS

    Author : Jonatan Kleimark; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alkene insertion; allylic alkylation; catalysis; cross coupling; density funtional theory; free energy surface; iron; kinetic investigation; Mizoroki-Heck reaction; nickel; palladium; reaction mechanism; sulfinylation; transition metal;

    Abstract : Transition metal catalyzed reactions have had a large impact on the human progress for the last century. Several extremely important areas, such as the agricultural industry and the plastic industry, have benefited from this development. READ MORE

  2. 7. Palladium-Catalysed Couplings in Organic Synthesis Exploring Catalyst-Presenting Strategies and Medicinal Chemistry Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alejandro Trejos; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mizoroki-Heck arylation; Suzuki coupling; domino reaction; stereoselective; palladium; chelation control; vinyl ether; HIV-protease inhibitors; HIV-integrase inhibitors; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Palladium-catalysed coupling reactions have been embraced by synthetic chemists as one of the preferred means for smooth formation of new carbon-carbon bonds: a truly ubiquitous methodology of synthesizing complex molecules.This thesis describes the study of a series of palladium(0)-catalysed C2-arylations of a 1-cyclopentenyl ether, equipped with a chiral (S)-N-methyl-pyrrolidine auxiliary.

  3. 8. Rearrangements to vinyl substituted hetero- and carbocycles : Total synthesis of siphonazole B and otherapplications in oxazole and saturated ringsynthesis

    University dissertation from Lund University

    Author : Filip Paulsen; Lunds universitet.; Lund University.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this thesis is to explore and develop new reactions for rapid generation of molecular complexity. Byenabling access to important molecules in a less wasteful and more cost-efficient manner such developmentbenefits the whole modern society, where increasingly complex molecules are needed to solve problems withinfields ranging from medicine, to materials sciences and the perfume industry.

  4. 9. Resolution of Dynamic Systems: Applications in Asymmetric Synthesis and Materials Science

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lei Hu; KTH.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : This thesis is built on the concepts of constitutional dynamic chemistry and dynamic kinetic resolution, where reversible covalent reactions are used to generate dynamics and kinetically controlled reactions are employed for resolution. The thesis is divided into two parts:The first section focuses on the study of dynamic systemic resolution, a concept derived from constitutional dynamic chemistry. READ MORE
