Development of selective non-metal based organocatalysts for asymmetric synthesis
This thesis is concerned with the design, synthesis and use of novel bifunctional organocatalysts for the asymmetric Michael addition of ketones and 1, 3 - dicarbonyl compounds to trans - ~ - nitrostyrene. Chapter 1 describes the concept of organocatalysis, including history and mode of action. A de...
