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 ...

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.

Enantioselective Desymmetrization of Diesters
The Journal of Organic Chemistry, 2014The desymmetrization of prochiral diesters with a chiral phosphoric acid catalyst to produce highly enantioenriched lactones in excellent yield is reported. The process is easily scaled and accommodates a variety of substitution patterns, many of which result in the generation of an enantioenriched all-carbon quaternary center.

Enantioselective Sensing by Luminescence
2010Enantiomeric analysis is one of the crucial points for the sensor technology, due to the increasing importance that enantiomerically pure compounds and drugs have in pharmaceutic and agrochemical applications. Enantiomeric luminescent sensors give different responses by interaction or reaction with chiral molecules, allowing one to assess their optical

Enantioselective Synthesis of (−)-Pentalenene
Organic Letters, 2007A short, enantioselective synthesis of (-)-pentalenene is described. Catalytic enantioselective cyclopropenation with (R,R)-Rh2(OAc)(DPTI)3 was used to set the absolute stereochemistry, and an intramolecular Pauson-Khand reaction of the resulting cyclopropenyne was used to establish the quaternary center.

Enantioselective cooperative catalysis
Organic & Biomolecular Chemistry, 2015This review focuses on enantioselective cooperative catalytic reactions, wherein two catalysts work simultaneously to form products which cannot be obtained by the use of a single catalyst alone, which have attracted considerable attention in recent years.
