Electrostatic Interactions in Asymmetric Organocatalysis. [PDF]

open access: yesAcc Chem Res, 2023
Electrostatic interactions are ubiquitous in catalytic systems and are often decisive in determining reactivity and stereoselectivity. However, a lack of understanding of the fundamental underlying principles has long stymied our ability to fully harness the power of these interactions.

Asymmetric Organocatalysis: A Survival Guide to Medicinal Chemists [PDF]

open access: yesMolecules, 2022
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]

open access: yesNature Communications, 2020
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]

open access: yesEuropean J Org Chem, 2023
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]

open access: yesBeilstein Journal of Organic Chemistry, 2012
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]

open access: yesJ Am Chem Soc, 2012
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 organocatalysis involving double activation

open access: yesTetrahedron Chem, 2022
Asymmetric organocatalysis contributed tremendously to the field of organic synthesis since year 2000. Considering the diversity of organocatalysts and their activation modes, chemists developed the double activation strategy, in which two distinct ...

The Emergence of Quinone Methides in Asymmetric Organocatalysis [PDF]

open access: yesMolecules, 2015
Quinone methides (QMs) are highly reactive compounds that have been defined as “elusive” intermediates, or even as a “synthetic enigma” in organic chemistry.
