Abstract
Methoxy or fluoro hydroindolenones and hydroquinolenones can be obtained by oxidation of the corresponding 4-substituted open-chain phenols with C6H5- I-(OCOCF3)(2) with methanol or pyridinium polyhydrogen fluoride followed by an intramolecular conjugate addition. The corresponding cycle 2,5-hexadien ones can be obtained directly by a similar oxidation of the bicyclic phenol s. (C) 1999 Elsevier Science Ltd. All rights reserved.
