- Benzocarbazole Synthesis via Visible-Light-Accelerated Rh(III)-Catalyzed C-H Annulation of Aromatic Amines with Bicyclic Alkenes
-
A visible-light-accelerated Rh(III)-catalyzed C-H annulation of aromatic amines with bicyclic alkenes for the synthesis of benzocarbazole derivatives was developed. In this approach, with the cooperation of rhodium catalysis and visible-light irradiation, various aromatic amines reacted with oxabicyclic alkenes and azabicyclic alkenes smoothly at room temperature, delivering the corresponding bridged oxa or aza tetrahydro benzocarbazoles in good to excellent yields. Moreover, a series of benzo[b]carbazoles were synthesized conveniently through further aromatization in one pot. The potential of this method was demonstrated via directing-group removal, derivatization, a scale-up reaction, and fluorescence investigations.

- Combined KOH/BEt3Catalyst for Selective Deaminative Hydroboration of Aromatic Carboxamides for Construction of Luminophores
-
The selective catalytic C-N bond cleavage of amides into value-added amine products is a desirable but challenging transformation. Molecules containing iminodibenzyl motifs are prevalent in pharmaceutical molecules and functional materials. Here we established a combined KOH/BEt3 catalyst for deaminative hydroboration of acyl-iminodibenzyl derivatives, including nonheterocyclic carboxamides, to the corresponding amines. This novel transition-metal-free methodology was also applied to the construction of Clomipramine and luminophores.

- Hydride-catalyzed selectively reductive cleavage of unactivated tertiary amides using hydrosilane
-
The first hydride-catalyzed reductive cleavage of various unactivated tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions.

- Direct synthesis of N -H carbazoles via iridium(III)-catalyzed intramolecular C-H amination
-
The iridium-catalyzed dehydrogenative cyclization of 2-aminobiphenyls proceeds smoothly in the presence of a copper cocatalyst under air as a terminal oxidant through intramolecular direct C-H amination to produce N-H carbazoles. A similar iridium/copper system can also catalyze the unprecedented dimerization reaction of 2-aminobiphenyl involving 2-fold C-H/N-H couplings.

- Synthesis of carbazoles by copper-catalyzed intramolecular C-H/N-H coupling
-
A Cu-catalyzed intramolecular C-H amination for the synthesis of carbazoles has been developed. The key to success is the installation of the picolinamide-based directing group, which is spontaneously removed after the coupling event. The Cu catalysis proceeded smoothly under Pd- and I(III)-free conditions, and its mild oxidation aptitude enables the rapid and concise construction of heteroatom-incorporated carbazole core π-systems.

- 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.

-
A microwave-enhanced Suzuki-Miyaura cross-coupling reaction in combination with a microwave-assisted Cadogan reductive cyclization is presented as an easy access to a variety of 2-substituted carbazoles and other fused heterocyclic systems. Microwave irradiation was found very useful in minimizing the proto-deboronation issues in the cross-coupling reaction, and enhances the rate of reductive cyclization in a dramatic manner.

- Pyrolysis of quinoline-3,4-dicarboxylic anhydrides bearing 2-phenyl, 2-benzyl and 2-o-tolyl substituents: Formation of products of carbene insertion and addition
-
Flash vacuum pyrolysis of 2-phenylquinoline-3,4-dicarboxylic anhydride at 800°/0.06 mm gave indeno[1,2-b]indole (30-40%), which readily added nucleophiles Y- at C-10 to give 5,10-dihydro derivatives (Y=H, Me, Ph, NEt2, OMe, CH(COOMe)2 and CMe2NO2). Similar pyrolysis of the 2-benzylquinoline anhydride gave a 1:2 mixture of the (expected) linear 5H-benzo[b]carbazole and the (unexpected) angular 7H-benzo[c]carbazole. The isomeric 2-o-tolylquinoline anhydride on similar pyrolysis gave mainly 11H-benzo[a]carbazole (85%), isomeric benzocarbazoles (4%) and 11H-indeno[1,2-b]quinoline (2.6%). Most of these products are probably derived from exocyclic carbenes formed by aryne-carbene equilibration, but the last compound may be formed by direct aryne-methyl interaction.
