Abstract

Atropisomers are compounds in which chirality arises from hindered rotation along the carbon–carbon or carbon–heteroatom single bond. Recently, organocatalysis appeared to be a rapid, valuable, and efficient strategy for their preparation in an enantioselective manner. In this report a general overview of the most important organocatalyzed atroposelective transformations will be given pointing out in particular the specific role played by the catalyst.
