1. 1. Samarium(II)-mediated Reactions in Organic Synthesis - Method Development and Mechanistic Investigation

   Författare :Tobias Ankner; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Samarium II iodide; reduction; single electron transfer; nitro group reduction; mechanistic study; bond cleavage; deoxygenation; additives; toluenesulfonyl deprotection; defluorination.;

   Sammanfattning : This thesis describes the development of methods using divalent samarium reagents in organic synthesis. The main focus is placed on functional group reductions, but reductive formation of carbon-carbon bonds has also been investigated. LÄS MER

3. 2. Carboligation using the aldol reaction : A comparison of stereoselectivity and methods

   Författare :Derar Al-Smadi; Mikael Widersten; Ulf Nilsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aldol reaction; cinchonine; FSA enzyme; homologation reactions; phenylacetaldehyde derivatives; samarium diiodide.;

   Sammanfattning : The research summarized in this thesis focuses on synthesizing aldehyde and aldol compounds as substrates and products for the enzyme D-fructose-6-aldolase (FSA). Aldolases are important enzymes for the formation of carbon-carbon bonds in nature. LÄS MER
