摘要

THE monocarboxylic sesquiterpene lactones having an unsaturated four-carbon side-chain attached to the cycloheptane ring are represented in nature by xanthatin and related compounds. Formerly, structures (I) and (11) were proposed for xanthatin and xanthinin respectively on the basis of ultraviolet and infrared studies. 2 Later, structure (111) was suggested for xanthinin on the basis of degradation studies; it differs only in the position of ...
