- 論文の詳細を見る
The structures of four new non-cardiac steroidal aglycones: ester A, fukujusone, adonilide and fukujusonorone, which had been isolated from the root of Adonis amurensis besides five other known substances, were discussed. Ester A is a nitrogen containing compound and was proved to be 12-O-nicotinoylisolineolon (IV). Fukujusone was given the structure of 3β,8β,14β-trihydroxy-5-pregnen-20-one (V) on chemical and physical basis. Adonilide is a γ-lactone and was assigned the structure of 14β,20α-epoxy-20β-hydroxy-18-oic acid lactone (IX). Fukujusonorone seems to be the first example of a genuine natural 18-norsteroid and was given the structure of 3β-hydroxy-18-norpregna-5,13(14)-dien-12,20-dione (XII). A sequence including β-keto acid decarboxylation was suggested as a possible mechanism of fukujusonorone biosynthesis, and its appliance in the chemical preparation of 18-norpregnanes was also stated.
