Synthesis of Tribenzo[ b, d, f]azepines via Palladium-Catalyzed Annulation Reaction of 2-Iodobiphenyls with 2-Halogenoanilines

A palladium-catalyzed annulation reaction of 2-iodobiphenyls with 2-halogenoanilines has been developed. A variety of 2-iodobiphenyls and 2-halogenoanilines can undergo this transformation. Diversified tribenzo[b,d,f]azepine derivatives can be synthesized in moderate to excellent yields according to this method.

Palladium-Catalyzed Dual Coupling Reaction of 2-Iodobiphenyls with o-Bromoanilines through C-H Activation: An Approach for the Synthesis of Tribenzo[ b, d, f]azepines

A novel and straightforward approach for the synthesis of tribenzo[b,d,f]azepines starting from 2-iodobiphenyls and 2-bromoanilines has been developed. A wide range of tribenzo[b,d,f]azepines were obtained in good to excellent yields via a cascade intermolecular palladium-catalyzed C-H activation/dual coupling reaction. C,C-palladacycles, which are generated by C-H activation of 2-iodobiphenyls, should be the reaction intermediates.

Synthesis of carbazoles by intramolecular arylation of diarylamide anions

(Chemical Equation Presented) The synthesis of a series of substituted 9H-carbazoles by the photostimulated SRN1 substitution reaction with diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches, the Pd-catalyzed reactions (Buchwald-Hartwig) or Cu-catalyzed reactions of 2-haloanilines with aryl halides, or 2-bromoiodobenzene with anilines, with moderate to very good isolated yields (45-89%). Through an intramolecular C-C bond formation of diarylamines by the SRN1 mechanism, carbazoles were achieved. These reactions proceeded synthetically in very good to excellent yields (81-99%) in liquid ammonia and DMSO. The reaction of N-(2-bromophenyl)-2-phenylbenzenamine gave 1-phenyl-9H-carbazole (38%) and the isomer 9H-tribenz[b,d,f]azepine (58%). By using this methodology, 9Hcarbazoles, substituted 9H-carbazoles, benzocarbazoles, and even 3,3′-bi(9H-carbazole) were obtained by a double SRN1 reaction with benzidine.

Preparation of 9H-Tribenzazepine and Its 1-Methoxy Derivative

Two convenient routes to 9H-tribenzazepine (2) have been developed.The first method involves the deoxygenation and hydrolysis of 1,4-dihydro-1,4-epoxy-9-acetyl-9H-tribenzazepine (8) employing low-valent titanium.The second method employs the reactive intermediate 10,11-didehydro-5-acetyl-5H-dibenzazepine (7) in a Diels-Alder reaction with 1,3-cyclohexadiene.The resulting cycloadduct 13 upon undergoing a retro-Diels-Alder reaction and hydrolysis yields 2. 1-Methoxy-9H-tribenzazepine (11) was prepared from ring opening of 8 to1-hydroxy-9-acetyl-9H-tribenzazepine (10) followed by methylation with dimethylsulfate and hydrolysis.
