Rearrangement of Allyl Aryl Ethers II, Reactions of Hydroquinones with Cycloalkenediols

Abstract

Cycloalkenobenzofurans are prepared in one operation from hydroquinone and cycloakenediol involving a sequence of acid-catalyzed formation of ether , 1,3- and 3,3-rearrangements, and acid-catalyzed intramolecular cyclization of intermediates generated.
