Abstract
A metal free, one-pot tandem synthetic routes for functionalized indole derivatives has been established. An efficient three-component reaction was designed with incorporation of Knoevenagel condensation followed by inter-, and intramolecular nucleophilic addition reaction in one-pot under mild condition. The structural diversities of the synthesized compounds have been confirmed spectroscopically, by IR, H-1- and C-13 NMR, and elemental analyses which agree with the proposed structures.
