Late acceleration of phosphoric acid-catalyzed Diels-Alder reaction by internal hydrogen-bonding of adjacent hydroxy group
The Bronsted acid-catalyzed Diels-Alder reaction was examined. Phosphoric acids were effective Bronsted acids for the Diels-Alder reaction of cyclohexadienones and activated by the internal hydrogen-bonding of the adjacent hydroxy group. (c) 2007 Elsevier B.V. All rights reserved.
