Multi-component reactions (MCR) are the most converging reaction in the synthetic field due to the creation of molecular functionality & diversity. MCR shows advantages of high atom economy & several bond formation capacities in a single step. Even though reaction needs easily available common starting material, they require drastic reaction conditions and suffer with side product formation, low yield & problems in recyclability of the catalytic system.<br/>2-amino-4H-chromene derivatives are synthesized through the MCR using a task specific ionic liquid with the intention to obtain high yield. The mild basicity of used ionic liquid, initialises the reaction through Knoevenagel condensation. Use of IL restricted self-condensation, thereby enhancing the yield of desired product. In addition to this given ionic liquid has added advantages like high yields with short reaction time, easy separation of product & reusability of ionic liquid.
