2-Fluoroalkyl-substituted indoles were prepared in moderate to excellent yields through bromotriphenylphosphonium salt promoted ring formation with fluorine-containing carboxylic acids in the presence of triethylamine in toluene at reflux temperature. A range of 2-fluoroalkyl-substituted indole derivatives can be conveniently prepared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
