Abstrakt: 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.
