Various 3-(1-aryl-9,10-dihydro-4-azaphenanthren-9-yl)coumarins 3a-o were synthesized by reacting various 3-coumarinoyl methyl pyridinium salts 1a-c with appropriate 2-benzylidene-1-tetralone 2a-e in the presence of ammonium acetate and acetic acid under the Kröhnke's reaction condition. The structures of all the synthesized compounds were established on the basis of elemental and spectral analysis.
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.
