Palladium-Catalyzed C-H Oxidation of Isoquinoline N-Oxides: Selective Alkylation with Dialkyl Sulfoxides and Halogenation with Dihalo sulfoxides

A novel palladium-catalyzed C?H oxidation of isoquinoline N-oxides has been developed for regioselectively synthesizing substituted isoquinolines. The method represents the first example of using dialkyl sulfoxides as the alkyl sources for the construction of 1-alkylated isoquinolines. Moreover, the regioselective halogenation of isoquinoline N-oxides is also successful using dihalo sulfoxides as the halide sources.

Synthesis of the new furo[3,2-h]isoquinoline alkaloid, TMC-120B from Aspergillus ustus

A total synthesis of a new furo[3,2-h]isoquinoline alkaloid TMC120-B (2), isolated from Aspergillus ustus together with two related compounds, has been completed in sixteen steps. The key step is the synthesis of the appropriate 3,7,8-trisubstituted isoquinoline framework (23) based on a thermal electrocyclic reaction of the 1-aza 6 pi-electron system involving the benzene double bond. In addition, the microwave assisted electrocyclic reaction of this system was newly performed.

Synthesis and reactivity of some imidazo-, triazolo- and tetrazolo-isoquinoline derivatives

1-Acetylimino-3-methyl-1H-isochromene-4-carbonitrile, 1, reacts with glycine ethyl ester under basic conditions to give an imidazo[2,1-a]isoquinoline derivative, while reaction with hydrazine hydrate in 1,4-dioxane, with further chemistry, provides access to [1,2,4]triazolo[5,1-a]isoquinoline, [1,2,4]triazolo[3,4a]isoquinoline and tetrazolo[5,1-a]isoquinoline analogs. Benzene ring nitration and radical bromination of substituent methyl groups were investigated in the four tricycles, with some different positional reactivities being found. Two bromomethyl derivatives so produced were oxidised; ethyl 2-bromomethyl-6-cyano-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate gave the anticipated ethyl 6-cyano-2-formyl-5-methylimidazo[2,1-a]isoquinoline-3-carboxylate (which reacted further with hydrazine to form a new system, 8,9-dihydro-6-methyl-8-oxopyridazino[4′,5′:4,5]imidazo[2,1-a]isoquinoline-5-carbonitrile), while 5-bromomethyl-2-methyl[1,2,4]triazolo[5,1-a]isoquinoline-6-carbonitrile unexpectedly gave directly another new system, 5,6-dihydro-5-hydroxy-2-methyl-7H-pyrrolo[3,4-c][1,2,4]triazolo[5,1-a]isoquinolin-7-one.

Chemopreventive activity of isoquinoline alkaloids from Corydalis plants

Eighteen isoquinoline alkaloids including protoberberines (1-12), benzophenanthridines (13-16) and an aporphine (17) isolated from plants of Corydalis species (Fumariaceae) were tested for inhibitory effects on Epstein-Barr virus early antigen activation induced by 12-O-tetradecanoylphorbol 13-acetate in Raji cells. In a primary screening test, all of the isoquinoline alkaloids showed inhibitory activity with the IC50 values being in the range of 140-410 mol ratio/32 pmol TPA. The data demonstrate that these isoquinoline alkaloids might be valuable as anti-tumor promoters.
