A rapid access to 3-indolyl-1-trifluoromethyl-isobenzofurans I [R1 = H, 5-Me, 6-F, etc.; R2 = H, 5-Me, 5-Br; R3 = H, Me, Et, Bn] via a [1,4]-hydride shift/cyclization/intermol. nucleophilic addition reaction sequence was reported. In this process, a Lewis acid promoted internal redox reaction ([1,4]-hydride shift/cyclization) followed by a Bronsted acid promoted intermol. reaction (generation of cyclic oxonium cation/intermol. Friedel-Crafts reaction) of indoles and (dibenzylamino)methyl-phenyl-trifluoro-ethanones occurred to give various 3-indolyl-1-trifluoromethyl-isobenzofurans in good chem. yields. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0Recommanded Product: 61150-57-0).
2-Bromo-4-fluorobenzylbromide (cas: 61150-57-0) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.Recommanded Product: 61150-57-0
