Three-component synthesis of 2-oxoindolin-3-ylphosphonates.
A one-pot, three-component and catalyst-free method for the efficient and simple synthesis of dialkyl 3-(dicyanomethyl)-2-oxoindolin-3-ylphosphonates at 50 degrees C under solvent-free conditions is reported. The features of this procedure are mild reaction conditions, high yields of products, and operational simplicity.
