摘要
Abstract We report a palladium‐catalyzed intramolecular direct heteroarylation of oxazole tethered β ‐naphthols to access corresponding tetracyclic 4 H ‐benzo[5,6]chromeno[3,4‐ d ]oxazoles. Various functional groups are well tolerated and furnished the desired products in good to excellent yields under the present reaction conditions. The scale‐up reaction and synthetic utility of the resulting molecules have been demonstrated. Moreover, UV/vis absorption and fluorescence emission properties have been evaluated for these polyheterocyclic compounds.
