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.
