The synthesis of a spirocyclic analog of huperzine A that bears a cyclopropane ring at its 10-position has been carried out in an enantioselective manner using a diastereoselective Michael–aldol reaction; in assays of AChE inhibition, this compound was found to be nearly as active as huperzine A itself, with comparable on and off rates from the enzyme.
使用非对映选择性迈克尔-羟醛反应以对映选择性方式合成了在 10 位带有环丙烷环的石杉碱甲螺环类似物;在 AChE 抑制测定中,发现该化合物的活性几乎与石杉碱 A 本身一样,并且酶的开启和关闭速率相当。
