A fast transition metal-free methodology for the synthesis of highly functionalized heterocycles was developed. The exploitation of formamide or N-methylformamide and potassium persulfate under microwave irradiation resulted in a reaction of 10 s. The functionalized oxindoles and dihydroquinoline-2-ones give access to several spirolactones and spiroimides.
