An efficient metal-free strategy for the synthesis of pharmaceutically relevant benzo[a]carbazoles from the derivatives of readily available 2-phenylindole and bio-renewable acetol in an aqueous biphasic system was developed. This protocol employed a sulfone-containing Broensted acidic ionic liquid as the catalyst, which could be used for five times without a noticeable decrease in its activity and selectivity. Various substituted 2-phenylindoles and alpha-hydroxyketones participated in the reaction smoothly, with water as the sole byproduct. Mechanistically, the reaction involved the conventional carbon-nucleophile-induced Heyns-type rearrangement and downstream intramolecular olefination.

New Advances in Chemical Research, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing theoretical assessments of solvent structures and their interactions with reaction intermediates. Application of 15804-19-0, We’ll be discussing some of the latest developments in chemical about CAS: 15804-19-0, name is Quinoxaline-2,3(1H,4H)-dione. In an article，Which mentioned a new discovery about 15804-19-0

N-Ureido-quinoxalinedione derivatives have been discovered as leads for a novel series of dipeptidyl peptidase-IV (DPP-IV) inhibitors through high-throughput screening of our chemical library. A brief structure-activity relationship of the compounds was investigated. Among them, entry 5 showed the most potent inhibitory activity. The nitro group in quinoxaline moiety and the aromatic sulfonyl substituted ureido functional group seem to be important to increase the potency dramatically.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 15804-19-0
