Simple and efficient copper(I)-catalyzed access to three versatile aminocoumarin-based scaffolds using isocyanoacetate

10.1002/adsc.201000895

The study presents an efficient method for the one-pot copper(I)-catalyzed synthesis of 3-aminocoumarin and its derivatives, which are biologically and pharmaceutically significant compounds. The researchers utilized salicylaldehyde, ethyl isocyanoacetate, and 2-aminopyridine as the primary starting materials, along with copper(I) salts (CuI, Cu(OTf)2, etc.) as catalysts, and pyridine as a base. These chemicals served to construct molecular scaffolds that are valuable in medicinal chemistry due to their potential applications as CNS depressants, antitumor, anti-inflammatory, and antimicrobial agents, as well as their use as fluorescent markers. The study aimed to develop a straightforward and efficient approach to these molecular scaffolds, which are considered "privileged structures" in the pharmaceutical and agrochemical industries.
