  An efficient synthesis of a new series of 5-amino-7-aryl-6-cyano-4H-pyrano[3,2-b]pyrrole derivatives from the reaction of 3-hydroxypyrrole, malononitrile, and various aromatic aldehydes using ZrOCl2·8H2O, an environmentally friendly catalyst under a thermal solvent-free green procedure is described. This simple protocol offer advantages such as shorter reaction times, simple work-up and excellent yield. The catalyst ZrOCl2·8H2O can be reused. The reusability of the catalyst has been studied for the synthesis of 5-amino-7-aryl-6-cyano-4H-pyrano[3,2-b]pyrrole. All the compounds were screened for their antibacterial and antifungal activity.

  Twelve new derivatives of 5-amino-7-aryl-6-cyano-4H-pyrano[3,2-b]pyrrole were prepared by one-pot acid-catalyzed cyclocondensation reaction of 3-hydroxypyrrole, malononitrile, and various aldehydes in the presence of the silica-supported ionic liquid 1-methyl-3-(triethoxysilylpropyl)imidazolium hydrogen sulfate as catalyst. The reaction efficiencies were enhanced by moderate electron-withdrawing groups, such Cl and Br, on benzaldehyde, but decreased as substituents became more electron-withdrawing. Among the solvents and catalysts screened for the model reaction, acetonitrile and the silica-supported hydrogen sulfate ionic liquid were found to be the best choices.
