Synthesis of a Series of 2-Indolylmethylene-Linked Compounds by Thermal Knoevenagel Condensation Under Catalyst- And Solvent-Free Conditions

Abstract

An efficient methodology has been developed by which a series of new 2-indolylmethylene-linked compounds can be readily synthesized by thermal Knoevenagel condensation of 3-methylindole-2-carboxaldehyde and cyclic active methylene compounds under catalyst-and solvent-free conditions. * Corresponding Authors E-Mail: mallikak52@yahoo.co.in [a]
