Photosensitized Oxidation of Isoeugenol in Protic and Aprotic Solvents

Abstract

Sensitized photooxygenation of isoeugenol gave seven products in methanol, seven products in ethanol, six products in acetone, and five products in acetonitrile. One of the products is a 7,7’-linked lignan of a type which has not yet been observed in nature. The structures of these products were elucidated and the mechanisms of their formation are discussed. © 1991, The Pharmaceutical Society of Japan. All rights reserved.
