Abstract

Formation of the photoproducts (10) and (12) and chemical and spectroscopic evidence suggest that kokoononol obtained from Kokoona zeylanica is 27-hydroxyfriedelane-3,21-dione (1); kokoondiol and kokoonol have been identified as 21α,27-dihydroxyfriedelan-3-one (2) and 27-hydroxyfriedelan- 3-one (3), respectively, by chemical conversions.
