Isatin chalcones and their 3‐hydroxy precursors are shown to possess potential anticancer activity and are also versatile substrates and key intermediates for the synthesis of a large variety of bioactive spiro‐oxindoles. An environmental friendly tandem synthesis, using PEG 400 as green solvent cum phase transfer catalyst, for a series of 3‐hydroxy‐2‐oxindoles and 3‐methylene‐2‐oxindoles has been
