Disclosed are 1,2,3,4,5,6,7,8-octohydro-9-phenylacetamidoacridine and the salt thereof, as well as the preparation method and medical use thereof. The compound can be useful for the preparation of medicaments for treating cardiovascular diseases, especially arrhythmia.
9-Amino-1,2,3,4-tetrahydro- and 9-amino-1,2,3,4,5,6,7,8-octahydroacridine derivatives (2 and 3) were conveniently prepared in the reduction of the corresponding 2-substituted 9-aminoacridines (la-f) with nickel-aluminum alloy under basic conditions. The reduction is dependent upon the nature of the substituent in the 2-position of the starting 9-aminoacridines.
The available methods of chemical synthesis have arguably contributed to the prevalence of aromatic rings, such as benzene, toluene, xylene, or pyridine, in modern pharmaceuticals. Many such sp2-carbon-rich fragments are now easy to synthesize using high-quality cross-coupling reactions that click together an ever-expanding menu of commercially available building blocks, but the products are flat and
