Martin-Mejias, Irene; Aragoncillo, Cristina; Yanai, Hikaru; Hoshikawa, Shoki; Fujimoto, Yuuki; Matsumoto, Takashi; Almendros, Pedro published an article in 2020, the title of the article was A catalyst-free bis(triflyl)ethylation/benzannulation reaction: rapid access to carbazole-based superacidic carbon acids from alkynols.Name: 1,5-Dimethyl-1H-indole-2-carbaldehyde And the article contains the following content:
Carbazoles possessing Tf2CHCH2 groups were obtained by the reaction of 1-(indol-2-yl)but-3-yn-1-ols with in-situ generated Tf2C=CH2 through vicinal difunctionalization of the alkyne moiety, where the vinyl-type carbocation intermediate was selectively attacked by the indole moiety and not by the carbanion moiety. The experimental process involved the reaction of 1,5-Dimethyl-1H-indole-2-carbaldehyde(cas: 883526-76-9).Name: 1,5-Dimethyl-1H-indole-2-carbaldehyde
The Article related to indolyl arylbutynol pyridiniumyl trifluoromethylsulfonyl ethanide regioselective triflylethylation benzannulation, aryl triflylethylcarbazole preparation, Heterocyclic Compounds (One Hetero Atom): Indoles, Indolizines, Carbazoles, and Other Arenopyrroles and other aspects.Name: 1,5-Dimethyl-1H-indole-2-carbaldehyde
