  6. 24. Developments in the Field of Aza-Diels-Alder Reactions, Catalytic Michael Additions and Automated Synthesis

    Author : Stefan Modin; Pher Andersson; Lars Engman; Hans Adolfsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Asymmetric synthesis; aza-Diels-Alder; Michael addition; Transfer hydrogenation; automated synthesis; Catalysis; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : The development of new aza-bicyclic structures with potential applications as ligands synthesised via an aza-Diels-Alder cycloaddition has been studied. The studies are concerning the i) development of large scale aza-Diels-Alder reaction, ii) development of a fast and simple route to bicyclic diamine ligands, iii) development of new aza-Diels-Alder adducts from different dienes, iv) development and application of bicyclic N,P ligands for catalytic Michael additions and v) development of robotized asymmetric transfer hydrogenation reactions.
