1. Expanding the H-phosphonate and H-phosphonothioate chemistry towards biologically important phosphate analogs
Sammanfattning : This thesis focuses on chemical transformations of H-phosphonate and H-phosphonothioate and can be divided in two parts. The first part, is devoted to the development of the palladium-catalyzed P-C bond formation. Both mechanistic and synthetic studies of the transformations have been performed. LÄS MER
2. Towards synthesis of biologically important phosphate analogues : exploring H-phosphonate and C-phosphonate chemistry
Sammanfattning : This thesis is based on studies directed towards the development of methods for the preparation of phosphorus containing natural products, with the focus on C-phosphonate nucleic acid analogues.Mechanistic studies concerning formation of the phosphorus-carbon bond resulted in development of two efficient protocols for the synthesis of C-phosphonates from the corresponding H-phosphonate derivatives.

3. Studies on Oxidative Couplings in H-Phosphonate Chemistry
Sammanfattning : In this thesis oxidative coupling of H-phosphonate and H phosphonothioate diesters with different alcohols and amines are presented. Since the reactions with alcohols previously have been particularly unfavourable due to competing side reactions, a modified protocol leading to high coupling yields of structurally diverse hydroxylic components was developed.
