Efficient synthesis of biscarbazoles by palladium-catalyzed twofold C-N coupling and C-H activation reactions

A new and efficient strategy for the synthesis of 3,9′- and 2,9′-biscarbazoles was developed. Our strategy relies on the cyclization of 1,1′-biphenyl-2,2′-diyl bis(trifluoromethanesulfonate) with 4- or 3-anisidine, transformation of the methoxy to a triflate group and subsequent oxidative Pd-catalyzed cyclization with various anilines.

METHOD FOR PRODUCING 9-(ARYLAMINO)ARYL-9H-CARBAZOLE

PROBLEM TO BE SOLVED: To efficiently produce 9-(arylamino)aryl-9H-carbazole. SOLUTION: A haloarylamine represented by formula (1) is reacted with a carbazole derivative in the presence of a palladium compound, a phosphine compound, and a metal alkoxide. (Each Ar is independently a phenylene group or the like, provided that the phenylene group or the like may be substituted with a C1-4 alkyl group or the like; each X is independently Cl, Br or I; p and q are each independently 1 or 2; each R1 is independently a C1-6 alkyl group, a phenyl group, a naphthyl group, a biphenylyl group or a pyridyl group; m is 1 or 2; n is 0 or 1; and m+n=2 is satisfied.)

Palladium-catalyzed Selective Amination of Aryl(haloaryl)amines with 9H-Carbazole Derivatives

Palladium-catalyzed amination of aryl(haloaryl)amines with 9H-carbazole derivatives was investigated. In the amination of (4-bromophenyl)phenylamine with 9H-carbazole by the use of Pd2(dba)3/PtBu3/NaOtBu catalyst, the main product was desired 9-[4-(phenylamino)phenyl]-9H-carbazole in 60% yield with conversion of (4-bromophenyl)phenylamine >99%, and the concomitant formation of 9-[4-[phenyl[4-(phenylamino)phenyl]amino]phenyl]-9H-carbazole (15% yield), which is the consecutive by-product, was observed. When XPhos was used instead of PtBu3, the desired product was provided in 81% yield and the consecutive by-product was suppressed to 7.7%. The yield of the desired product reached 98% by the use of tBu-XPhos. Such excellent yields of the desired product were also obtained with other 2-di-tert-butyl- or 2-di(1-adamantyl)phosphino-1,1’-biaryls. Various 9-(arylamino)aryl-9H-carbazoles could be synthesized from aryl(haloaryl)amines and 9H-carbazole derivatives in high yields by the use of tBu-XPhos. The amination of 4-bromotoluene with a mixture of diphenylamine and 9H-carbazole gave only 9-o-tolyl-9H-carbazole with tBu-XPhos, while the use of PtBu3 or XPhos afforded the mixture of 9-o-tolyl-9H-carbazole and diphenyl(o-tolyl)amine, indicating that Pd2(dba)3/tBu-XPhos/NaOtBu catalyst high selectively favors 9H-carbazole over diphenylamine as an amination substrate.
