Hydrazones as Singular Reagents in Asymmetric Organocatalysis [PDF]

open access: yesChemistry - A European Journal, 2016
AbstractThis Minireview summarizes strategies and developments regarding the use of hydrazones as reagents in asymmetric organocatalysis, their distinct roles in nucleophile–electrophile, cycloaddition, and cyclization reactions. The key structural elements governing the reactivity of these reagents in a preferred pathway will be discussed, as well as ...

ASYMMETRIC ORGANOCATALYSIS

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 ...

Applications of asymmetric organocatalysis in medicinal chemistry

Chem. Soc. Rev., 2013
In the last decade, organocatalysis, the use of small chiral organic molecules as catalysts, has proven to be a valuable and attractive tool for the synthesis of enantiomerically enriched molecules. A number of organocatalysts and processes, such as one-pot, tandem, cascade or multicomponent reactions, have been reported to date.

A Chiral Solvent Effect in Asymmetric Organocatalysis

Organic Letters, 2010
Proline-catalyzed aldol reactions between enolizable ketones and aromatic aldehydes can be carried out in propylene carbonate. When enantiomerically pure propylene carbonate is used, the combination of (R)-proline and (R)-propylene carbonate constitutes a matched pair, while (S)-proline and (R)-propylene carbonate constitutes a mismatched pair.

The Importance of Organocatalysis (Asymmetric and Non‐Asymmetric) in Agrochemicals

ChemistrySelect, 2023
Abstract Organocatalysis has been well established and documented for the asymmetric and non asymmetric synthesis of pharmaceuticals, natural products and fine chemicals. However, relatively a few reports have been reported regarding the synthesis of chiral or achiral agrochemicals while using organocatalysis.
