Isolation and structures of two novel neolignans, asatone (1) and isoasatone (2), 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.
本文描述了两种新型新木质素--asatone (1) 和 isoasatone (2) 的分离和结构。后者的结构是通过对其二羟基衍生物进行 X 射线晶体学分析而确定的,与其化学和光谱数据完全一致。此外,还从生物遗传学的角度对这些新木质素及其衍生物进行了热反应和光化学反应。其中,asatone 在光化学作用下转化为异asatone。
