  4. 7. Mechanistic Studies of Organocopper Chemistry by NMR Spectroscopy: Conjugate Additions to Alkynes and Alkenes

    Author : Karolina Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanocuprate; organocopper reagents; ynones; lithium dimethylcuprate; 13C and 15N NMR spectroscopy; pi-complexes; mechanism; enoates; 6Li; 1H-HOESY; ynoates; conjugate addition;

    Abstract : This thesis focuses on the mechanisms of organocopper reactions, in particular the reactions with activated alkynes (ynoates and ynones). These reactions are of interest in the formation of new highly functionalized double bonds with control of the stereochemistry. READ MORE

  5. 8. Conjugate priors for Bayesian object tracking

    Author : Yuxuan Xia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian estimation; object tracking; multi-object smoothing; backward simulation; automotive radar; extended object; conjugate prior; random finite sets; multi-object tracking; sets of trajectories.;

    Abstract : Object tracking refers to the problem of using noisy sensor measurements to determine the location and characteristics of objects of interest in clutter. Nowadays, object tracking has found applications in numerous research venues as well as application areas, including air traffic control, maritime navigation, remote sensing, intelligent video surveillance, and more recently environmental perception, which is a key enabling technology in autonomous vehicles.

  6. 9. Exploring Conjugate Addition Activity in Pseudozyma antarctica Lipase B

    Author : Maria Svedendahl; Per Berglund; Olof Ramström; Amelie Eriksson Karlström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B · conjugate addition · enzyme catalysis · enzyme catalytic promiscuity · molecular modeling; Biochemistry; Biokemi;

    Abstract : Multifunctional enzymes have alternative functions or activities, known as “moonlighting” or “promiscuous”, which are often hidden behind a native enzyme activity and therefore only visible under special environmental conditions. In this thesis, the active-site of Pseudozyma (formerly Candida) antarctica lipase B was explored for a promiscuous conjugate addition activity. READ MORE

  7. 10. Towards Rational Design of Asymmetric Catalyst for Organometallic and Organocatalytic Reactions

    Author : Antti Hartikka; Per Arvidsson; Albrecht Berkessel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organocatalysis; Transition Metal Complex; Asymmetric; Aldol Reaction; Cyclopropanation; Diels-Alder; Reduction; Conjugate Addition; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with synthetically modified chiral molecules and their application in asymmetric catalysis. The first part of the thesis describes the use of commercially available chiral diamine ligands in the iridium catalyzed transfer hydrogenation of aromatic ketones. READ MORE
