Indium trifluoromethanesulfonate (In(OTf)3). A novel reusable catalyst for intramolecular Diels–Alder reactions
摘要:
Indium trifluoromethanesulfonate (In(OTf)(3)) is found to be an effective catalyst for intramolecular Diels-Alder reactions of furans. This novel catalyst, soluble in both aqueous and organic media, is easily recovered from the aqueous layer after the reaction is completed. (C) 2000 Elsevier Science Ltd. All rights reserved.

The preparation of substituted N-arylisoindolines 3 from simple furan derivatives 1 is reported. Oxatricycloadducts 2, readily accessible by intramolecular Diels-Alder reaction are susceptible to acidic reagents yielding aromatized products 3 by a ring-opening reaction via intermediate carbocation.
