1. C1 Building Blocks: New Approaches for Thiomethylations and Esterification
Sammanfattning : The thioether motif is found in numerous pharmaceuticals. The simplest form of this motif, the methyl-thioether is similarly found in many biologically active compounds and has exhibited many advantageous properties. The installation of the thiomethyl moiety can be troublesome due to the toxicity and malodor of small sulfur reagents. LÄS MER
2. Metal Mediated Synthesis. Synthetic and Mechanistic Investigations of Conjugate Addition and Reductive Amination
Sammanfattning : The thesis is divided into two separate parts, one treating conjugate addition and the other reductive aminations. The first part of the thesis is concerned with organocopper promoted conjugate addition to .alfa.,. LÄS MER
3. Model Systems for Metal - DNA Interactions. With a Focus on Anticancer Active Platinum(II) Complexes
Sammanfattning : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. LÄS MER
