Alkylidenephosphoranes in heterocyclic synthesis: Reactivity of benzoxazinones with resonance-stabilized phosphorus ylides
2H-3,1-Benzoxazine-2,4(1H)-dione and its N-methyl analogue react with alkylidenephosphoranes to give substituted quinolines and benzazepines as well as indanone and furan derivatives. Reaction mechanisms to explain the formation of products obtained are outlined. Georg Thieme Verlag Stuttgart.
