《Imidazolone-activated donor-acceptor cyclopropanes with a peripheral stereocenter. A study on stereoselectivity of cycloaddition with aldehydes》 was published in Chemistry of Heterocyclic Compounds (New York, NY, United States) in 2020. These research results belong to Mikhaylov, Andrey A.; Solyev, Pavel N.; Kuleshov, Andrei V.; Kublitskii, Vadim S.; Korlyukov, Aleksander A.; Lushpa, Vladislav A.; Baranov, Mikhail S..

Nucleophilic cyclopropanation of arylideneimidazolones possessed a peripheral chiral center and the subsequent fractional crystallization of diastereomers allowed access to the compounds with an enantiomerically uniform configuration of the spirocyclic donoracceptor cyclopropane fragment. The mechanism of the cycloaddition reaction with aldehydes; it was demonstrated that stereochem. information from the cyclopropane fragment was lost during the reaction. In addition to this study using Trimethylsulfoxonium iodide, there are many other studies that have used Trimethylsulfoxonium iodide(cas: 1774-47-6Recommanded Product: 1774-47-6) was used in this study.
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides.Recommanded Product: 1774-47-6
