A novel and regioselective Ni(I) catalyzed C-C and C-N cascade coupling reactions has been developed. The cascade furnishes atom-economic access to 40 3-aryl-1-aminoisoquinolines. The regioselectivity of C(sp3)-cyano group over C(sp2

Melted poly(ethylene glycols) (PEGs) were used for the first time as solvent for the sonochemically promoted cyanation of aryl halides employing inexpensive and safe K4[Fe(CN)6] and a relatively low amount of Cu-based catalyst. The Mw (weight-average polymer molecular weight) of PEG proved to notably influence the substrate conversion, which is indicative of a strong dependence of the sonication efficacy on solvent properties. Gel permeation chromatography (GPC), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) contributed to the characterization of the polymer and the elucidation of the catalytic system. Off the PEG: Melted poly(ethylene glycol)s (PEG)s were used for the first time as solvent for the sonochemical cyanation of aryl halides using K 4[Fe(CN)6] and a relatively low amount of Cu catalyst (5 %). The weight-average molecular weight of PEG was proven to exert a notable influence on conversion, and CuI proved to be the most efficient catalyst, affording good results within short reaction times with the use of aryl iodides and activated aryl bromides as substrates.

6-Butyl-5,6-dihydrobenzimidazo[2,1-a]isoquinoline, 3,9- and 3,10-dimethoxy, and 3,9- and 3,10-dihydroxy analogues, and their 12-methyl quaternary salts were prepared by a multistep route. Cytotoxicities against 55 human cancer cell lines were measured in the National Cancer Institute screen. The quaternary salts of the dimethoxy compounds (15b/c) were clearly the most active overall, with a mean graph midpoint (MGM) value of 2 μm.
