Asymmetric organocatalysis in drug discovery and development for active pharmaceutical ingredients

Expert Opinion on Drug Discovery, 2022
Introduction Over the last 20 years, it has become clear that organocatalysis is the third pillar of catalysis. The low reactivity in the early days of organocatalysis has been overcome with the invention of more efficient catalysts, and by harnessing ...

Organocatalysis: A recent development on stereoselective synthesis of o-glycosides

Catalysis reviews, 2022
Organocatalysis is the use of non-stoichiometric amounts of low-molecular-weight organic molecules made up of C, H, N, O, S, and P to accelerate stereoselective chemical transformations.

Bifunctional N-Heterocyclic Carbenes Derived from l-Pyroglutamic Acid and Their Applications in Enantioselective Organocatalysis.

Accounts of Chemical Research, 2020
ConspectusIn nature, enzymes are a powerful medium for the construction of enantiomerically pure chemicals, which always inspires synthetic chemists to explore new catalysts to imitate the enzyme machinery for asymmetric transformations.

Construction of Axially Chiral Compounds via Asymmetric Organocatalysis.

Accounts of Chemical Research, 2018
Axially chiral compounds have received much attention from chemists because of their widespread appearance in natural products, biologically active compounds, and useful chiral ligands in asymmetric catalysis. Because of the importance of this structural

Organocatalysis in Inert C-H Bond Functionalization.

Chemical Reviews, 2017
As two coexisting and fast-growing research fields in modern synthetic chemistry, the merging of organocatalysis and C-H bond functionalization is well foreseeable, and the joint force along this line has been demonstrated to be a powerful approach in ...
