Novel palladium-catalyzed synthesis of 1,2-dihydro-4(3H)-carbazolones
摘要:
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. (C) 2002 Elsevier Science Ltd. All rights reserved.
Palladium-catalyzed synthesis of 1,2-dihydro-4(3H)-carbazolones. Formal total synthesis of murrayaquinone A
摘要:
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.

Reduction of 2-(2-nitrophenyl)-2-cyclohexene-1-ones using palladium on carbon under 1 atm of hydrogen gas at ambient temperature affords 1,2,3,4-tetrahydrocarbazoles in excellent isolated yields. The starting materials were prepared by intermolecular Stille coupling of 2-iodo-2-cyclohexen-1-ones with 2-(tributylstannyl)-1-nitrobenzenes.

[reaction: see text] Palladium[0]-mediated Ullmann cross-coupling of o-halonitrobenzene (1) and various related nitroarenes with a range of alpha-halo-enones (e.g., 2) or -enals readily affords the expected alpha-arylenones, e.g., 3, or -enals, which are converted into the corresponding indoles, e.g., 4, on reaction with dihydrogen in the presence of Pd on C.

The present invention relates to methods for the synthesis of indoles. In particular, the invention relates to the coupling of an a-haloenone or a-haloenal with an ortho-halonitroarene to form an ortho-(enone)nitroarene or ortho-(enal)nitroarene. Reductive cyclization of an ortho-(enone)nitroarene or ortho-(enal)nitroarene affords access to indole compounds.
