Pd catalyzed desymmetrization of cis-3,5-dibenzoyloxycyclopent-2-ene combined with a diastereoselective epoxidation provided a common intermediate that can bifurcate to form either (−)-neplanocin A or its 2,3-di-epi isomer.
对映体选择性Pd催化的顺式3,5-二苯甲酰氧基环戊-2-烯的非对称化与非对映体选择性环氧化反应提供了可以分解成(-)-neplanocin A或其2,3-di-epi异构体的常见中间体。
