Facile Preparation of Flavinium Organocatalysts

ChemSusChem, 2016
AbstractWe developed a safe, simple, inexpensive, and environmentally benign method for preparing N(5)‐ethylated flavinium organocatalysts without using hazardous reagents or inert conditions as previously required. 5‐Ethyl‐3‐methyllumiflavinium cation was prepared from its reduced form by NaNO2‐free aerobic oxidation, which was subsequently extracted ...

Polymeric chiral organocatalysts

Polymer Chemistry, 2011
Incorporation of a chiral quaternary ammonium salt into a polymer allows for the preparation of a polymeric chiral organocatalyst that can be utilized in various asymmetric transformations in organic synthesis. Chiral quaternary ammonium salts are among the most important and frequently used organocatalysts.

Alkaloid Synthesis Using Organocatalysts

2018
This chapter covers the literature since the advent, in the 21st century, of total syntheses of alkaloids using enantio- or diastereoselective organocatalytic reactions to construct the alkaloid scaffolds. The details of these alkaloid syntheses are described separately for each basic skeleton, including indole, indoline, oxindole, and piperidine ...

Catalysis with Supported Organocatalysts

2011
Asymmetric organocatalysis is a rapidly growing area of modern organic chemistry. Organocatalysts can be used for electrophilic substitutions in α-position of saturated aldehydes and ketones as well as for nucleophilic additions to nitroethenes and α,β-unsaturated aldehydes and ketones. Organocatalysed cycloadditions are also described. In recent years
