The new facile approach has been developed for the synthesis of spiro [diindenopyridine-indoline] triones under the umbrella of green chemistry. The developed protocol is endowed with the use of low transition temperature mixture as a green reaction medium, operational simplicity, easy workup procedures, good to excellent product yields, and non-chromatographic purification procedure. Since indenone fused motifs have a broad spectrum of biological activities, this protocol is expected to find application in the combinatorial synthesis of biologically active compounds.

A one-pot, pseudo four-component method for the efficient and simple synthesis of spiro[diindeno[1,2-b: 2',l'-e]pyridine-11,3'-indoline]-2',10,12- trione derivatives in refluxing acetonitrile is reported. The features of this procedure are mild reaction conditions, high yields of products, and operational simplicity.
