Abstract

Abstract The acid catalyzed isomerization of several substituted oxanorbornadienes 4 and oxepines 10-easily available from 4 by a photochemical and a consecutive thermal step- allows the synthesis of several highly substituted phenols and 2, 4-cyclohexadienones in a straightforward manner and with good to excellent yields. The formation of the methoxycarbonyl-hexadienes 18e and 18f upon photolysis of 9e and 17f in methanol ...
