A novel one-pot N-S bond cleavage of tosyl hydrazones derivatives of isatin and fluorenone by (het)arynes was discovered. The reaction produced diverse diaryl and heteroaryl-aryl sulfones as major products and...
An efficient method for the construction of the quinazolinone skeleton from the reaction of 9-(phenylethynyl)-9H-fluoren-9-ols with substituted 2-aminobenzamides catalyzed by boron trifluoride is achieved. Scope of the reaction with a...
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.
