Abstract

The reactions of phloroglucinol with α,β-unsaturated dinitriles (or malononitrile and carbonyl compounds) lead to the formation of hitherto unknown 2,8-diamino-5-hydroxy-4H,10H-pyrano[2,3-f]chromene-3,9-dicarbonitriles. The reaction conditions and the structure of the products were studied in details.
