B+[4+2]: 3-Borylbenzine reagieren in Diels-Alder-Reaktionen mit substituierten Furanen und Pyrrolen in guten bis perfekten Regioselektivitäten zu hochfunktionalisierten Arylboronsäure-Derivaten (siehe Bild). Der Einfluss der Boryl-Gruppe auf die Regioselektivität ist auf elektronische Effekte zurückzuführen. [source]

Total Synthesis of Murrayanine Involving 4,5-Dimethyleneoxazolidin-2-ones and a Palladium(0)-Catalyzed Diaryl Insertion

HELVETICA CHIMICA ACTA, Issue 8 2007
Pablo Bernal
Abstract A new total synthesis of the natural carbazole murrayanine (1) was developed by using the 4,5-dimethyleneoxazolidin-2-one 12 as starting material. The latter underwent a highly regioselective Diels,Alder cycloaddition with acrylaldehyde (=prop-2-enal; 13) to give adduct 14 (Scheme,3). Conversion of this adduct into diarylamine derivative 9 was carried out via hydrolysis and methylation (Scheme,4). Differing from our previous synthesis, in which such a diarylamine derivative was transformed into 1 by a PdII -stoichiometric cyclization, this new approach comprised an improved cyclization through a more efficient Pd0 -catalyzed intramolecular diaryl coupling which was applied to 9, thus obtaining the natural carbazole 1 in a higher overall yield.
