An oxazine ring was annelated to benzopyran-4-one and benzopyran-2-one cores by reacting 7-hydroxyisoflavones and 7-hydroxycoumarins with lupinylamine and formalin. The new derivatives 9,10-dihydro-4H,8H-chromeno[8,7-e][1,3]oxazin- 4-one and 9,10-dihydro-2H,8H-chromeno[8,7-e][1,3]oxazin-2-one containing a lupinine moiety in the 9-position were prepared.
