1. 1. Optimering i organisk syntes : betingelser, system, syntesvägar

   Författare :Lars Hansson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; Response surface method; PLS method; Silylation; Enolether; Unsaturated ketones; Diketones; Geosmin synthesis; Onepot procedure;

   Sammanfattning : This thesis deals with different optimization problems encountered in organic synthesis. The use of response surface, sequential simplex and PLS techniques, for simultanious optimization of yield and suppression of side reactions is investigated. This is illustrated by an example of enamine synthesis, were a side reaction was a serious problem. LÄS MER

3. 2. Metal‐Free Arylations of Oxygen and Nitrogen Nucleophiles : Applications of Diaryliodonium Salts

   Författare :Elin Stridfeldt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; arylation; aryloxyamines; cyclization; diaryliodonium salts; O-aryloximes; sigmatropic rearrangement;

   Sammanfattning : This thesis concerns development of new methods for metal‐free arylations in organic synthesis. The protocols discussed in the thesis are based on a class of hypervalent iodine compounds called diaryliodonium salts. These reagents are known to transfer aryl moieties to suitable nucleophiles.
