Synthesis of imidazol[1,5-a]indole-1,3-diones from imidazolidene-2,4-diones

Copper and tributyltin hydride catalysed cyclization, through the N-aryl bond formation, of imidazolidine-2,4-diones (11-16,18) yielded imidazo[1,5-a]indole-1,3-diones (5-10) in high yields (72-100%). The ease of cyclization was found to be consistent with the normal halogen reactivity and the type of substituents. The highly substituted imidazole-2,4-dione 15 gave brominated 19 and tin incorporated heterocycles 20 when treated with copper bromide and tributyltin hydride, respectively.
