Enhancing the Potential of Enantioselective Organocatalysis With Light [PDF]

Nature, 2018
Organocatalysis - catalysis mediated by small chiral organic molecules - is a powerful technology for enantioselective synthesis, and has extensive applications in traditional ionic, two-electron-pair reactivity domains.

Atroposelective Organocatalysis

Angewandte Chemie - International Edition, 2011
The stereochemical phenomenon that arises from hindered rotation around bonds in nonplanar molecules is termed atropoisomerism.] The presence of a stereogenic axis is the distinct feature in these molecules. One type of atropoisomeric molecule is generated when bulky substituents are placed at the ortho positions of an aryl ring such that there is ...

Enantioselective Organocatalysis

Angewandte Chemie International Edition, 2001
The last few years have witnessed a spectacular advancement in new catalytic methods based on metal-free organic molecules. In many cases, these small compounds give rise to extremely high enantioselectivities. Preparative advantages are notable: usually the reactions can be performed under an aerobic atmosphere with wet solvents.

Organocatalysis with dendrimers

Chemical Society Reviews, 2012
This review gives an overview of the use of dendrimers and dendrons as organocatalysts, i.e. as catalysts in the absence of any metal. A large variety of dendrimeric structures have already been used for such a purpose, varying in size (generation), type and location (core or surface) of the organocatalytic entities, and overall chemical composition ...

Alkynes in Organocatalysis

Asian Journal of Organic Chemistry, 2014
AbstractIn this Focus Review, a selection of organocatalyzed reactions in which alkynes have been used are presented. Catalysis by tertiary and secondary amines, by phase‐transfer catalysis, by phosphines and carbenes, as well as bifunctional and multiple catalysis are discussed.
