Asymmetric Organocatalysis: From Infancy to Adolescence [PDF]

open access: yesAngewandte Chemie - International Edition, 2008
AbstractAfter an initial period of validating asymmetric organocatalysis by using a wide range of important model reactions that constitute the essential tools of organic synthesis, the time has now been reached when organocatalysis can be used to address specific issues and solve pending problems of stereochemical relevance.

Cinchona Alkaloids in Asymmetric Organocatalysis [PDF]

open access: yesSynthesis, 2010
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

Asymmetric Supramolecular Organocatalysis: A Complementary Upgrade to Organocatalysis [PDF]

open access: yesEuropean Journal of Organic Chemistry, 2017
The recent past has witnessed tremendous growth in the field of asymmetric synthesis through “asymmetric supramolecular organocatalysis (ASO)”. ASO emerges from many interactions between substrates and catalysts: namely substrate–catalyst, catalyst–catalyst and substrate–substrate interactions.

Activation of Carboxylic Acids in Asymmetric Organocatalysis [PDF]

open access: yesAngewandte Chemie - International Edition, 2014
AbstractOrganocatalysis, catalysis using small organic molecules, has recently evolved into a general approach for asymmetric synthesis, complementing both metal catalysis and biocatalysis.1 Its success relies to a large extent upon the introduction of novel and generic activation modes.2 Remarkably though, while carboxylic acids have been used as ...

Catalyst design within asymmetric organocatalysis [PDF]

open access: yesWiley Interdisciplinary Reviews: Computational Molecular Science, 2022
The field of organocatalysis, more specifically asymmetric organocatalysis, is continuously expanding having grown significantly over the recent years. However, despite this exponential expansion, the ability to determine with any degree of certainty the

Asymmetric Organocatalysis in Deep Eutectic Solvents [PDF]

open access: yesEuropean Journal of Organic Chemistry, 2021
The recent advances in asymmetric organocatalysis using eutectic mixtures as a reaction medium are revised in this mini-review. In addition, the first enantioselective transformations using chiral eutectic solvents, which play the role of a green medium ...

Green Asymmetric Organocatalysis

ChemSusChem, 2020
AbstractAsymmetric organocatalysis is becoming one of the main tools for the synthesis of chiral compounds that are needed as medicines, crop protection agents, and other bioactive molecules. It can be effectively combined with various green chemistry methodologies.
