Bicyclic Ligands and Catalysts in Asymmetric Synthesis

Popular Abstract in Swedish Asymmetrisk katalys är ett omfattande forskningsområde där ett flertal olika typer av enantioselektiva katalysatorer har utvecklats och använts i en mängd olika kemiska reaktioner med varierande resultat. Det finns ingen katalysator som fungerar lika väl i alla applikationer, utan resultaten varierar från fall till fall och för vissa typer av substrat behövs det därför Synthesis of compounds based on the structurally rigid bicyclo[2.2.2]octane and the dibenzobicyclo[3.3.1]nonane frameworks and also their application as ligands and catalysts in asymmetric synthesis are described. For the synthesis of 1,3-diols based on the bicyclo[2.2.2]octane framework, an improved synthesis of the starting material bicyclo[2.2.2]octan-2,6-dione was developed and performed at 0

Three scenarios for globalisation. A view from cultural semiotics

Three scenarios for globalisation. A view from cultural semiotics Göran Sonesson Using the concept of the auto-model, this text describes global society as a device people use to understand their relation to other cultures. Three scenarios are analysed in terms of a model each : first, we consider the hypertrophy of the Internal Other, which results from the displacements of sizeable populations

Tooth wear in wild boar (Sus scrofa).

In order to study the limitations and possibilities of age estimation based on tooth wear of skeletal remains from wild boar, 315 mandibles from five different populations of wild boar from Poland, Germany and Sweden were analysed. Asymmetric tooth wear between the right and left mandibles was found to be rare and no systematic difference in tooth wear between males and females (less than 36 month

Substituting computers for services - potential to reduce ICT's environmental footprint

The environmental footprint of IT products are significant and, in spite of manufacturing and product design improvements, growing consumption of electronics results in increasing absolute environmental impact. Computers have short technological lifespan and a lot of the in-build performance, although necessary, remains idling for most of the time. Today, most of computers used in non-residential
