An efficient and iron-catalysed synthesis of 4H-pyrano[3,2-b]pyrrole is reported. The reactions proceed through a one-pot, three component cyclocondensation of 3-hydroxypyrrole, malononitrile and various aldehydes to afford 4H-pyrano[3,2-b]pyrrole derivatives in moderate to good yield using ferric hydrogensulphate, Fe(HSO4)3, as the catalyst.

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-m
