Asymmetric Organocatalysis: A Survival Guide to Medicinal Chemists [PDF]
Majority of drugs act by interacting with chiral counterparts, e.g., proteins, and we are, unfortunately, well-aware of how chirality can negatively impact the outcome of a therapeutic regime.

Advances in asymmetric organocatalysis over the last 10 years [PDF]
Organocatalysis has become a major pillar of (asymmetric) catalysis. Here, the authors discuss recent trends in organocatalytic activation modes for challenging stereoselective transformations and the emerging integration with other fields, such as ...

Recent Developments and Trends in Asymmetric Organocatalysis [PDF]
AbstractAsymmetric organocatalysis has experienced a long and spectacular way since the early reports over a century ago by von Liebig, Knoevenagel and Bredig, showing that small (chiral) organic molecules can catalyze (asymmetric) reactions. This was followed by impressive first highly enantioselective reports in the second half of the last century ...

Mechanochemistry assisted asymmetric organocatalysis: A sustainable approach [PDF]
Ball-milling and pestle and mortar grinding have emerged as powerful methods for the development of environmentally benign chemical transformations. Recently, the use of these mechanochemical techniques in asymmetric organocatalysis has increased.

Cross-trienamines in Asymmetric Organocatalysis [PDF]
Cross-conjugated trienamines are introduced as a new concept in asymmetric organocatalysis. These intermediates are applied in highly enantioselective Diels-Alder and addition reactions, providing functionalized bicyclo[2.2.2]octane compounds and γ'-addition products, respectively.

Asymmetric Conjugate Hydrocyanation of α,β-Unsaturated Aldehydes Catalyzed by Engineered 2-Deoxy-D-ribose-5-phosphate Aldolase. [PDF]
The power of catalytic promiscuity: The enantioselective conjugate hydrocyanation of enals remains a long‐standing challenge for biocatalysis. Here, we report the redesign of 2‐deoxy‐D‐ribose‐5‐phosphate aldolase for the asymmetric conjugate hydrocyanation of aromatic enals, expanding the reaction scope of iminium‐based enzyme catalysis to include an ...

Cinchona Alkaloids in Asymmetric Organocatalysis [PDF]
This article reviews the applications of cinchona alkaloids as asymmetric catalysts. In the last few years, characterized by the resurgence of interest in asymmetric organocatalysis, cinchona derivatives have been shown to catalyze an outstanding array of chemical reactions, often with remarkable stereoselectivity. This work presents an overview of the
