Reactions with mleimides X+: Synthesis of several new pyrrolidino-and pyrrolo [4,3-b] furochromone derivatives for biological activity screening

Several new pyrrolidino- and pyrrolo-[4, 3-b] furochromone derivatives were synthesized via the dipolar cycloaddition reactions of some styrylfurochromones with N-arylmaleimide and subsequent dehydrogenation. Structures are confirmed by elemental analysis and spectral data studies
