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

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

    Sammanfattning : 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.

  7. 5. Kunskapsfrågan : En läroplansteoretisk studie av den svenska gymnasieskolans reformer mellan 1960-talet och 2010-talet

    Författare :Carl-Henrik Adolfsson; Daniel Sundberg; Stefan Lund; Lisbeth Lundahl; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; politics of knowledge; educational reform; curriculum content; governing mechanism; socioeconomic change; upper secondary school; critical realism; teacher; pupil; critical discourse analysis; discursive shifts; Pedagogics and Educational Sciences; Pedagogik och Utbildningsvetenskap;

    Sammanfattning : In a society where the labour market is becoming increasingly knowledge intensive and more differentiated, education has assumed greater importance for the capitalist states integrative functions as for the competitiveness in the global economy. As a consequence, the educational system has become a key governing resource for the state to meet and manage different kinds of social changes and problems. LÄS MER
