A library of novel 1-methyl-4-arylpyrrolo-(spiro(2.2']indan-1',3'-dione)-spiro[3.3 '']-1 ''-methyl/benzyl-5 ''-(arylmethylidene)piperidin-4 ''-ones and 1-methyl-4-arylpyrrolo-(spiro[2.11']-11H-indeno(1,2-b]quinoxaline)-spiro[3.3 '']-1 ''-methyl/benzyl-5 ''-(arylmethylidene)piperidin-4 ''-ones have been synthesized via 1,3-dipolar azomethine ylide cycloaddition in the ionic liquid, 1-butyl-3-methylimidazolium bromide ([BMIm]Br), in excellent yields.
