概要

• 論文の詳細を見る

• Isolation and structures of two novel neolignans, asatone (<B>1</B>) and isoasatone (<B>2</B>), are described. The structure of the latter, established by means of an X-ray crystallographic analysis of its dihydroxy derivative, is in full agreement with its chemical and spectral data. From a biogenetic point of view, furthermore, thermal and photochemical reactions of these neolignans and their derivatives were carried out. In particular,asatone was photochemically converted into isoasatone.
