The use of proline as catalyst for the aldol process has given a boost to the development of organocatalysis as a research area. Since then, a plethora of organocatalysts of diverse structures have been developed for this and other organic transformations under different reaction conditions. The use of an organic molecule as catalyst to promote a reaction meets several principles of Green Chemistry. The impleme Read More

The careful selection of a suitable chiral backbone is vital for the preparation of any modern ligand for asymmetric catalysis, where binaphthyl based ligands are considered paradigmatic and systematically used in a diversity of asymmetric catalysed reactions, with emphasis for organocatalysis. Due to the vastness of possible organocatalytic applications, this review article is mainly focused on the asymmetric ald Read More

This mini-review reports an overview of the most promising applications of chiral ionic liquids as organocatalysts for asymmetric reactions such as the asymmetric direct aldol, Michael addition, Diels-Alder and Baylis-Hillman reactions, as well as future perspectives for industrial applications. Recent publications have reported the development of novel chiral ionic liquids and their potential application as unique chiral reaction Read More

In this non-comprehensive short review, we will highlight the usefulness of organocatalyis for the asymmetric synthesis of biological active compounds, ranging from apparently simple molecules to complex natural products.

Chiral phosphonates find many applications in medicine, agriculture, materials science and also in organic synthesis. The rapid growth of asymmetric organocatalysis in the last decade has sparkled the interest of organophosphorus chemists, and a wealth of new methodologies to obtain chiral phosphonic acid derivatives has been developed in recent years. This review surveys the last five years, and it includes met Read More

The current work discussed the criteria that control the non-enzymatic and enzymatic antioxidant activity from a chemical point of view. Two tunable strategies were classified to emphasize the reactivity of non-enzymatic one from the thermodynamic and kinetic perspectives. On the other hand, the non-covalent interactions and the intermediacy of reactive compounds formation were found to be the most efficient to Read More

Pfitzinger reaction is the formation of derivative of 4-quinoline carboxylic acids from isatins or its analogs under alkaline condition. This reaction was first discovered by Pfitzinger at the end of 19th century hence it is known as Pfitzinger reaction. This reaction has attracted a great deal of attention in the last few decades because of biological significance of quinoline carboxylic acid derivatives. The utility of Pfitzinger reacti Read More
