Efficient and convenient synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives mediated by L-proline

Abstract
An efficient, four-component, one-pot condensation reaction of phthalimide or phthalic anhydride, aromatic aldehydes, and ethyl cyanoacetate for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives mediated by L-proline in excellent yields is reported. GRAPHICAL ABSTRACT
