Components of the root of Lindera strychnifolia Vill. Part XV. Absolute configuration of linderalactone, linderane, and isolinderalactone and its derivatives

Abstract

In order to clarify the stereochemistry of linderalactone (I) and linderane (XXI), components of the root of Lindera strychnifolia Vill., the absolute configuration of isolinderalactone (II), a Cope rearrangement product of (I), was elucidated. From this result and from n.m.r. spectral data, the absolute configurations of (I) and (XXI) were also clarified.
