   Sammanfattning : This thesis deals with the development of new methods for efficient synthesis and analysis in asymmetric catalysis. It focuses on the preparation of chiral cyanohydrins by enantioselective addition of cyanide to prochiral aldehydes. LÄS MER

3. 2. Development and Studies of the Processes Involved in Minor Enantiomer Recycling

   Författare :Anna Laurell Nash; Christina Moberg; Karl Anker Jørgensen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; biocatalysis; cyanohydrins; dual activation; Lewis acid; Lewis base; minor enantiomer recycling; recycling; titanium; Kemi; Chemistry;

   Sammanfattning : This thesis describes the development and rationalization of processes involved in a new methodology developed in our group, minor enantiomer recycling.The first part of the thesis addresses mechanistic studies of one of the reactions involved in minor enantiomer recycling, dual Lewis acid-Lewis base catalyzed acetylcyanation of aldehydes.
