Alkaloids, limonoids and furocoumarins from three Mexican Esenbeckia species
Dreyer, David L.
, p. 941 - 944 (1980)
The chemical constituents of three Mexican Esenbeckia species have been determined. Rutaevin was the main limonoid present in the seeds of all three species, E. litoralis, E. flava and E. berlandieri. The husks, leaves, wood and bark contained a wide array of known furocoumarins and furoquinoline alkaloids. In addition, 1-hydroxy-3-methoxy-N-methylacridone was obtained from E. litoralis bark and a new natural 2-quinolone alkaloid, formulated as 3,3-diisopropyl-N-methyl-2,4-quinoldione, was obtained from E. flava wood. The structure was assigned from spectroscopic considerations and conversion to N-methylhaplofoline.
Synthesis of o -(dimethylamino)aryl ketones, acridones, acridinium salts, and 1 H -indazoles by the reaction of hydrazones and arynes

A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in good to excellent yields.
Directed ortho and remote Metalation - Cross coupling connections. Buchwald-Hartwig synthesis of 2-carbamoyl diarylamines. Regioselective anionic routes to acridones, oxindoles, dibenzo-[b,f]azepinones, and anthranilate esters

, p. 419 - 421 (2007/10/03)
2-Carboxamido diarylamines 1f, 7, and 9, efficiently available by Buchwald-Hartwig C-N cross coupling reactions, serve as starting materials for new anionic routes to acridones 2d, oxindoles 10, dibenzo[b, f]azepinones 11, and anthranilate esters 8.
