Abstract:An efficient and transition metal-free C(sp 3 )À H sulfonylation method is described for the synthesis of 2sulfolmethyl quinolines from 2-methylquinolines and the inexpensive sulfonyl hydrazides. Generally, this protocol uses KI as an additive in the presence of the oxidant tert-butyl peroxybenzoate (TBPB), an efficient and compatible benign method that delivers 2-sulfolmethyl quinolines products in moderate to good yields.
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.
