A compound of Formula (la), Formula (lb) or Formula (Ic), or a form thereof, wherein the dashed lines represent one or more double bonds optionally present where allowed by available valences.
Palladium-catalyzed synthesis of 1,2-dihydro-4(3H)-carbazolones. Formal total synthesis of murrayaquinone A

, p. 6323 - 6332 (2007/10/03)
Two sequential palladium-catalyzed reactions are the key steps in a novel synthetic route to 1,2-dihydro-4(3H)-carbazolones. The steps are an intermolecular Stille cross-coupling followed by a reductive N-heteroannulation. A formal total synthesis of murrayaquinone A, employing this sequence, is reported.

Two sequential palladium-catalyzed reactions are the key steps in a novel synthetic route to carbazolones, an intermolecular Stille coupling followed by a recently developed palladium-catalyzed reductive N-heteroannulation. A number of functionalized 1,2-dihydro-4(3H)-carbazolones were prepared using this sequence.

The stabilities of various salts of the 2,2,6,6-tetramethylpiperidine-1-oxonium ion were studied. 2,2,6,6-Tetramethylpiperidine-1-oxonium tetrafluoroborate was shown to react with 1,2,3,4-tetrahydrocarbazole (1-H-2,3,4,9-tetrahydrocarbazole) to give, in the presence of water, 4-keto-1,2,3,4-tetrahydrocarbazole in good yield.Under the same conditions, cyclopentindole and cycloheptindole gave the corresponding keto derivatives.In the absence of water, the oxidation of tetrahydrocarbazole gave a mixture of dimers, probably derived from the Diels-Alder self condensation of 1-H-2,3-dihydrocarbazole.The condensation is reversible and, in acid, the dimer mixture gives a salt of 1-H-2,3-dihydrocarbazole which can be reduced with sodium borohydride to give back tetrahydrocarbazole.
