Synthesis of 2-dimethylamino-3-hetaryl-5-hydroxybenzofurans by the nenitzescu route from nitro-containing enamines of the benzofuran series

Article abstract of DOI:10.1007/BF02269537

Enamines of the benzofuran series which contain nitro groups in the benzene ring of benzofuran or in 3-benzoyl substituent react with benzoquinone to form 2-dimethylamino-3-(substituted benzo-2-furyl)-5-hydroxybenzofurans.
