Abstract

With regard to green chemistry, atom-efficient transformations of easily available starting materials into complex organic building blocks become increasingly important. Here, a novel four-component condensation of ninhydrin, 1,2-phenylene diamine, proline and N-aryl maleimides to some new spiro pyrrolizidines via 1,3-dipolar cycloadditions of azomethine ylides, under microwave irradiation or classical conditions, is reported.
