Green Asymmetric Organocatalysis
ChemSusChem, 2020AbstractAsymmetric 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.

Organocatalysis with dendrimers
Chemical Society Reviews, 2012This review gives an overview of the use of dendrimers and dendrons as organocatalysts, i.e. as catalysts in the absence of any metal. A large variety of dendrimeric structures have already been used for such a purpose, varying in size (generation), type and location (core or surface) of the organocatalytic entities, and overall chemical composition ...

Deconstructing Covalent Organocatalysis
Angewandte Chemie International Edition, 2015AbstractModern organocatalysis has rapidly evolved into an essential component of contemporary organic synthesis. One of the most distinctive aspects of organocatalytic processes is the biomimetic nature in which the catalyst engages the substrate, often forming covalently bound intermediates in a manner reminiscent of enzyme catalysis.

Enantioselective Phosphine Organocatalysis
Synlett, 2009The broad potential synthetic usefulness of phosphine-promoted reactions has stimulated many recent investigations on enantioselective variants of known reactions of this family, as well as the search for new, specifically designed, chiral phosphorus catalysts.

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.

Non-asymmetric organocatalysis
Chemical Communications, 2012Asymmetric organocatalysis is now an established methodology for the preparation of chiral compounds. However, these are not the only valuable molecules which can be conveniently obtained. Organocatalytic reactions affording achiral compounds are gaining momentum, opening unexplored pathways in the synthesis of densely functionalized aromatic moieties,

Organocatalysis is a new and fast growing research area, especially for asymmetric synthesis. Compared to metal catalysis and biocatalysis, organocatalysis has a number of unique features such metal-free, mild reaction conditions, novel mode of activations, and good structural amenability. Fluorous organocatalysis provides an efficient way for catalyst

Asymmetric Supramolecular Organocatalysis: A Complementary Upgrade to Organocatalysis
European Journal of Organic Chemistry, 2017The 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.

This chapter provides a guide to the use of organocatalysis as a general catalytic concept in synthetic chemistry and aims to demonstrate the fundamental ideas and reasoning that lie behind the most popular strategies in this area. The key to the rapid growth in this field within the least two decades lies in an improved understanding of the different ...

INDIAN DRUGS, 2021
Dear Reader, Two basic reactions that were taught to us in the organic chemistry courses were the aldol condensation reaction and the Diels-Alder reaction. In aldol condensation, discovered by the French chemist Charles Wurtz in 1872, an enolate ion reacts with a carbonyl compound in the presence of an acid/ base catalyst to form a β-hydroxy aldehyde ...
