1. Lewis Acid Mediated Alkylation and Diels-Alder Reactions of 2H-Azirines
Abstract : This thesis describes the use of 2H-azirines as reactivesubstrates in Lewis acid catalysed nucleophilic additions andin the Diels-Alder reaction.A number of carbon nucleophiles have been added to aseries of 2H-azirines in the presence and absence ofBF3·Et2O. READ MORE

2. Lewis acid Mediated Aza-Diels-Alder Reactions and Asymmetric Alkylations of 2H-azirines
Abstract : This thesis describes the use of 2H-azirines, three-membered unsaturatednitrogen-containing heterocycles, as reactive intermediates ina number of Lewis acid promoted alkylations and Diels-Alderreactions providing synthetically useful aziridines. In order to carry out this investigation a new generalprocedure for the ring closure of vinyl azides, forming theresultant 3-substituted-2H-azirines, was developed applying low boiling solventsin closed reaction vessels at elevated temperatures.

3. Guiding Concepts : Essays on Normative Concepts, Knowledge, and Deliberation
Abstract : This thesis addresses a range of questions about normativity, broadly understood. Recurring themes include (i) the idea of normative ‘action-guidance’, and the connection between normativity and motivational states, (ii) the possibility of normative knowledge and its role in deliberation, and (iii) the question of whether (and if so, how) normative concepts can themselves be evaluated.

4. Thermal comfort and energy in residential buildings in a cold climate
Abstract : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. READ MORE
