The synthesis of enantiomeric phytoprostane B1 type II methyl esters has been accomplished in approximately 30% overall yield via two basic transformations starting from 3-[(dimethoxyphosphoryl)methyl]cyclopentenone as a key reagent. They include ethylation of the ring C(2) carbon and a Horner olefination reaction using the phosphonate moiety at C(3). The novel components of the Horner reaction, the
通过以3-[((二甲氧基磷酰基)甲基]环戊烯酮为关键试剂的两个基本转化,对映体植物前列腺素B 1 II型甲酯的合成以约30%的总收率完成。它们包括环C(2)碳的乙基化和使用C(3)处的膦酸酯部分进行的霍纳烯化反应。通过外消旋9-羟基-10-十一碳烯酸酯通过不对称的Sharpless环氧化(动力学拆分),然后进行臭氧分解,可以很容易地制备霍纳反应的新组分,即对映体9-甲酰基-9-羟基纳米酸酯。
