A series of spiroheterocycles were synthesized by a three component, one pot condensation of acenaphthylene-1,2-dione, malononitrile/ethyl cyanoacetate and β-diketone using [bmim][OH] as a novel basic ionic liquid catalyst. The products were identified by 1H NMR, IR and MS techniques. The present methodology offers several advantages such as milder conditions, simple operation, shorter reaction time, environmental friendliness and accessibility of catalyst.

Key words: basic ionic liquid, one pot, three component, spiroheterocycle
