SUBSTITUTED CALIX (4) PYRROLES AND PROCESS FOR THE SYNTHESIS OF CALIX (4) PYRROLES OVER MOLECULAR SIEVE CATALYSTS

摘要

The present invention relates to novel calix pyrroles and a process for synthesis of calix (4) pyrroles by reacting pyrrole with cyclic or acyclic ketones in dichloro methane (DCM) solvent over molecular sieve catalysts which provides an eco-friendly, more economical and selective heterogeneous method.
