Atroposelective Organocatalysis
Angewandte Chemie International Edition, 2011The 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, 2001The 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, 2012This 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 ...

Enantioselective organocatalysis
Drug Discovery Today, 2007Enantioselective organocatalysis has emerged as a powerful synthetic paradigm that is complementary to metal-catalysed transformations and has accelerated the development of new methods to make diverse chiral molecules. The operational simplicity, ready availability of catalysts and low toxicity associated with organocatalysis makes it an attractive ...

Organocatalysis is a new and fast growing research area, especially for asymmetric synthesis. Compared to metal catalysis and biocatalysis, organocatalysis has a number of unique features such metal-free, mild reaction conditions, novel mode of activations, and good structural amenability. Fluorous organocatalysis provides an efficient way for catalyst
