Melamine trisulfonic acid: A new, efficient and reusable catalyst for the synthesis of some fused pyranopyrrole derivatives
Synthesis of a new series of 5-amino-7-aryl-6-cyano-4H-pyrano[3,2-b]pyrrole derivatives has been reported. The cyclocondensation synthesis proceeded by the one-pot reaction of 3-hydroxypyrrole, malononitrile and various aromatic aldehydes in the presence of melamine trisulfonic acid (MTSA). The proc...
