Abstract A general and practical one‐pot synthesis of naphthopyran derivatives using hexadecyltrimethylammonium bromide (HTMAB) as catalyst (10 mol%) is described. This method provides several advantages such as neutral conditions, high yields and simple workup procedure. The catalyst is low cost, facile, active, environmentally friendly, and reusable. In addition, water is chosen as a green solvent

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.
