A one-pot three-component route for the direct introduction of dithiocarbamates into indoles using a C-H sulfenylation strategy mediated by molecular iodine is disclosed. Various indole derivatives including 1-methylindole, 2-methylindole, 3-methylindole, and 5-substituted indoles were applied successfully in this protocol to afford diverse indole-dithiocarbamates containing the dithiocarbamate group on the position two or three in good to high yields. The reactions do not require transition metals or disulfiram but use an environmentally benign solvent and simple commercially available starting materials.
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.
