 Title    Synthesen von Heterocyclen, 199 1 Spiro-lactone aus 1.2.3-Trioxo-2.3-dihydro-phenalen sowie 2.3.4-Trioxo-1.2.3.4-tetrahydrochinolinen und Anthranilsäure The Chemistry of Vicinal Triketones, VIII 1 Spiro Lactones from l,2,3-Trioxo-2,3-dihydro-phenalene and 2,3,4-Trioxo-l,2,3,4-tetrahydro-quinolines with Anthranilic Acid  
 Abstract    l,2,3-Trioxo-2,3-dihydro-phenalene (PT) and l,2,3-trioxo-2,3,6,7-tetrahydro-l H, 5H- benzo[ij]quinolizine (TMCHi) react with anthranilic acid (AS) primarily to give the spirolactones la-lb, which are thermically rearranged to the corresponding benzoxazine carboxylic acids 2 a - 2 b . l-phenyl-2,3,4-trioxo-l,2,3,4-tetrahydro-quinoline (PHCHi) reacts with AS yielding the spirolactone 1 c, which decomposes upon heating.
