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.

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.

Enantioselective organocatalysis

Drug Discovery Today, 2007
Enantioselective 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 in Inert C-H Bond Functionalization.

Chemical Reviews, 2017
As two coexisting and fast-growing research fields in modern synthetic chemistry, the merging of organocatalysis and C-H bond functionalization is well foreseeable, and the joint force along this line has been demonstrated to be a powerful approach in ...
