Organocatalytic Cycloaddition Reactions and Mechanistic Investigations

点击翻译按钮获取中文摘要

Among a large number of organocatalytic reactions, cycloaddition reactions catalyzed by nucleophilic organocatalysts have been well developed, since they represent one of the most commonly used and efficient methods to access carbo- and heterocyclic compounds due to their high efficiency, very mild reaction conditions, and easy recycling of catalysts. However, the mechanisms leading to high regio- and stereoselectivities still lack systematic research. Within this Joint Sino-German Research Project, we intend to investigate organocatalytic cycloaddition reactions and their related mechanisms using a combination of experimental and theoretical techniques, and further to develop new reaction modes and to explore new substrates and mechanisms, which will benefit the synthesis of core structures of natural products. The methodological diversity of the involved research groups is expected to offer particularly high synergies.
