Ortho esters Knoevenagel reaction

The Knoevenagel condensation of alkyl orilio-nitroaiylacetates and ortho-nitroarylacetonitriles with aliphatic aldehydes proved to give the corresponding alkylidene nitriles and esters [191-194]. In the presence of a base these nitriles undergo cyclization into indole or quinoline derivatives, depending on the reaction...
