Arylsulfonyl compounds are among the most important compounds in pharmaceutical and medicinal chemistry. Hence, a wide variety of sulfonylation methods have been reported recently. This review summarizes arylsulfonylation methodologies developed in the last 5 years and includes two major categories. The first entails direct arylsulfonylation and the second multicomponent arylsulfonylation. In direct arylsulfonylation, arylsulfonyl reagents react with C−H activated compounds, alkynes, and alkenes through coupling or addition reactions. In multicomponent reactions, arylation reagents and various substrates react with sulfur dioxide surrogates, such as DABSO, Na 2 S 2 O 5 , and K 2 S 2 O 5 . Arylsulfonyl hydrazides, aryl boronic acids, aryl silanes, and aryl halides are the most widely employed arylation reagents that react with sulfur dioxide surrogates to generate an arylsulfonyl source, and ensuing reactions proceed via pathways analogous to those of direct arylsulfonylation.
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.
