The Mechanism of Formation of 3H,9H-Pyranoindol-3-ones from 3-Indolalkanoic Acids

The mechanism of the formation of 1-methyl-3H,9H-pyranoindol-3-one (4) from the corresponding 3-indolacetic acid 1 is discussed.The suggested mechanism is substantiated by the isolation of a stable intermediate 2 and its transformations in the presence of acetic anhydride and/or Lewis acids.
