    • Quantitative examination of seed oils by chromatographic procedures 

      Badami, Rajashekhar Chanabasappa (University of St Andrews, 1962) - Thesis

    • Search for practical alternatives to organotin hydrides 

      Baguley, Paul A. (University of St Andrews, 1998) - Thesis
      A summary of the tin hydride method of generating radicals in organic synthesis is presented, followed by illustrative examples of other methods available for mediating radical reactions, with a particular emphasis on ...

    • New reagents and syntheses in heterocyclic organoselenium chemistry 

      Speirs, Richard Allan (University of St Andrews, 1986) - Thesis
      The main aim of this project was to develop new reagents capable of exchanging selenium for oxygen under mild conditions, to obtain new carboselenaldehyde (1) and selone (2) compounds. Phenylphosphonoselenoic dichloride ...

    • Studies on threonine synthase 

      Neal, Tracy (University of St Andrews, 1998) - Thesis
      Threonine synthase (TS, EC 4.2.99.2), catalyses a β,γ-replacement reaction to convert (2S)-0-phosphohomoserine (32) into (2S,3S)-threonine (33). Although threonine as an essential amino acid is vital to all lifeforms, the ...

    • Mechanistic studies on threonine synthase 

      Barclay, Fiona (University of St Andrews, 1995) - Thesis
      Threonine synthase catalyses the conversion of (2S)-0-phosphohomoserine to (2S,3R)-threonine with the elimination of phosphate. A novel and efficient synthesis of (2S)-0-phosphohomoserine has been developed starting from ...
