Ma, Jinliang published the artcileMetal-Free-Catalyzed Three-Component [2+2+2] Annulation Reaction of [60]Fullerene, Ketones and Indoles: Access to Diverse [60]Fullerene-Fused 1,2-Tetrahydrocarbazoles, Category: benzothiophene, the main research area is ketone indole fullerene iodine catalyst three component cycloaddition; fullerene tetrahydrocarbazole preparation.
The first example of metal-free-catalyzed multicomponent annulation reaction of [60]fullerene was developed for concise and efficient construction of novel [60]fullerene-fused 1,2-tetrahydrocarbazoles. Using inexpensive and readily available I2 as a catalyst, [60]fullerene, ketones, and indoles underwent a formal [2+2+2] annulation process to conveniently assemble diverse 1,2-tetrahydrocarbazoles. Mechanistic studies indicated that this reaction proceeded through I2-promoted generation of a 3-vinylindole structure with the characteristics of a conjugated diene followed by cycloaddition to [60]fullerene.
Organic Letters published new progress about [2+2+2] Cycloaddition reaction. 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Category: benzothiophene.
