Synthesis of Binuclear Isoquinoline- and Pyridine-Fused Benzimidazole-4,7-diones by Magnetic MOF-199-Catalyzed C-C Coupling/Cyclization Followed by Oxidation

2-(2-bromoaryl)-4,7-dimethoxy-1H-benzo[d]imidazoles and (Z)-2-(2-bromovinyl)-4,7-dimethoxy-1H-benzo[d]imidazoles react with 1,3-diketones by microwave irradiation in DMF in the presence of a catalytic amount of recyclable Fe3O4@SiO2@MOF-199 along with a base to give binuclear isoquinoline- and pyridine-fused benzimidazoles, respectively. Treatment of such binuclear N-fused hybrid scaffolds with ceric ammonium nitrate in acetonitrile/H2O or HBr/FeCl3 in H2O affords binuclear isoquinoline- and pyridine-fused benzimidazole-4,7-diones in good to high yields.

Access to functionalized isoquinoline N-oxides via sequential electrophilic cyclization/cross-coupling reactions

Electrophilic cyclization of 2-alkynylbenzaldoximes with various electrophiles leads to the formation of 4-iodoisoquinoline N-oxides or 4-bromo-isoquinoline N-oxides under mild conditions. The reaction can be transferred to highly functionalized isoquinoline N-oxides via palladium-catalyzed cross-coupling reactions.

Synthesis, aggregation -induced emission of a new anti-B18H22-isoquinoline hybrid

A novel compound (B18H20(NC9H7)2) was synthesized by connecting isoquinoline moieties to the anti-B18H22. The fluorescence emission performance in tetrahydrofuran/water mixtures showed that the compound had obvious aggregation-induced emission characteristic. Upon addition of water in tetrahydrofuran (90:10, v/v) solution, the quantum yield is increased by 0.04-1.41%. The photophysics properties of B18H20(NC9H7)2/ polystyrene and B18H20(NC9H7)2/anti-B18H22/polystyrene film were also studied, and the testing results show that these two films have a wide range of absorption in the visible region. Our work broadens the structure types of anti-B18H22 derivatives and provides a new way to develop new anti-B18H22 fluorescent materials containing isoquinoline units.

11H-indolo[3,2-c]isoquinoline has been synthesized in two steps starting from 4-bromoisoquinoline and 2-bromoaniline via a selective Buchwald-Hartwig reaction followed by a Pd-catalyzed intramolecular direct arylation involving C(sp(2))-H activation. The synthesis of 7H-indolo[2,3-c]isoquinoline was achieved by a combination of a Suzuki reaction with an intramolecular nitrene insertion reaction starting from 4-bromoisoquinoline and {2-[(2,2-dimethylpropanoyl)amino]phenyl}boronic acid. Selective methylation of the tetracyclic skeletons yielded the title compounds 6-methyl-6H-indolo[3,2-c]iso-quinoline and 6-methyl-6H-indolo[2,3-c]isoquinoline, which have never been described in the literature before.
