A simple, clean, environmentally benign route to the synthesis of 2-amino-chromenes is described using K2CO3 as a green catalyst in water under microwave irradiation. This implies a convenient route avoiding the usage of hazardous organic solvents and organic bases. This technique requires only water in both the reaction step and workup, thus rendering the whole procedure into a truly ecofriendly green protocol. All the synthesized compounds were shown to possess antibacterial activity as tested in vitro against standard strains of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus.
Substituted 2-amino-4H-chromenes have been efficiently synthesized in aqueous K2CO3 and their in vitro antibacterial activities were evaluated against standard strains of bacteria using Broth Microdilution MIC method.Figure optionsDownload as PowerPoint slide
