1. Organocopper compounds and iodotrimethylsilane in stereoselective conjugate additions
Sammanfattning : .... LÄS MER
2. Bridging McMurry and Wittig in One-Pot : Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes
Sammanfattning : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.

3. Stereoselective Synthesis of Amino Alcohols : Applications to Natural Product Synthesis
Sammanfattning : This thesis is divided into four separate parts with amino alcohols as the common feature. The first part of the thesis describes the development of an efficient three-component approach to the synthesis of α-hydroxy-β-amino esters. LÄS MER
4. Stereoselective syntheses of semichemicals : Applications in ecological chemistry
Sammanfattning : This thesis describes the syntheses of semiochemicals and their applications in the development of control methods for pest insects. The compounds synthesized are divided into three groups: 1) Lepidoptera pheromones; 2) methyl substituted chiral pheromones and 3) aphid pheromones. LÄS MER
5. Lewis acid promoted endocyclic cleavage of glycosides and related acetals
Sammanfattning : This thesis is a summary of five papers concerning endocyclic cleavage of glycosides and related acetals. Simple lactol ethers undergo endocyclic cleavage to give acyclic chain extended products on treatment with organoaluminium and organotitanium reagents. LÄS MER
