PMA/SiO2 as efficient, cost-effective and recyclable catalytic system for the synthesis of highly substituted pyrroles

A mild and efficient method for the synthesis of highly substituted pyrroles is described using phosphomolybdic acid supported on silica gel as a reusable catalyst. The use of PMA supported on silica gel makes it quite simple, more convenient and environmentally benign. This method offers several advantages such as high conversions, short reaction times, cleaner reaction profiles and the use of inexpensive and readily available catalyst.
