8-methylenedioxyquinoline with (+)-peroxycamphoric acid furnished a (–)-epoxide which was converted via a (+)-secondary monoformate into the (+)-diol, orixine. The absolute stereochemistry of the alkaloid is discussed.
用(+)-过氧樟脑酸氧化2,4-二甲氧基-3-(3-甲基丁-2-烯基)-7,8-亚甲基二氧基喹啉可提供(-)-环氧化物,可通过(+)-仲一甲酸酯转化到(+)-二醇,奥利辛中 讨论了生物碱的绝对立体化学。
