Abstract
beta-Alkoxy-substituted alpha,beta-unsaturated carbonyl compounds activated with an additional electron-withdrawing substituent undergo a facile tande m transetherification/intramolecular hetero Diels-Alder reactions when reac ted with delta,epsilon-unsaturated alcohols under thermal conditions. These reactions are stereoselective producing the corresponding functionalized h ydropyranopyran derivatives in good yields. (C) 1999 Elsevier Science Ltd. All rights reserved.
