Abstract

An empirical rule between the lactone configuration and the chem. shift of a-position hydrogen of lactone carbonyl (i.e. 11-Ha) in a series of dihydroarteannuin B compounds was proposed. On the basis of this rule, the lactone configuration of deoxyarteannuin degradation product I was assigned as b-cis, which was further proved by its synthesis. The reaction mechanism was also discussed.

Key words: LACTONES, CHEMICAL SHIFT, ARTEANNUIN, EPOXIDE, CONFIGURATION, DEGRADATION PRODUCTS
