Faltracco, Matteo; Damian, Matteo; Ruijter, Eelco published an article in 2021. The article was titled 《Synthesis of Carbazoles and Dihydrocarbazoles by a Divergent Cascade Reaction of Donor-Acceptor Cyclopropanes》, and you may find the article in Organic Letters.Recommanded Product: Trimethylsulfoxonium iodide The information in the text is summarized as follows:
An alkylation/olefination cascade of indolecarboxaldehydes and phosphonate-functionalized donor-acceptor cyclopropanes affords functionalized dihydrocarbazoles and cyclohepta[cd]indoles in formal [3 + 3] and [4 + 3]-cycloadditions A minor modification to the reaction conditions also allowed access to the fully aromatic heterocyclic scaffolds by thermal loss of an electron-rich aryl moiety.Trimethylsulfoxonium iodide(cas: 1774-47-6Recommanded Product: Trimethylsulfoxonium iodide) was used in this study.
Trimethylsulfoxonium iodide(cas: 1774-47-6) is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides.Recommanded Product: Trimethylsulfoxonium iodide
