Perhydrolysis of a sterically congested multifunctional epoxide was achieved in ethereal H2O2 with the aid of a recently developed Mo catalyst. The resulting hydroperoxide cyclized to give a 1,2,4‐trioxane, which could be readily elaborated into qinghaosu and a range of novel analogues. Some of the compounds with two such trioxane moieties showed in vitro antimalarial activity comparable to or even
借助最近开发的 Mo 催化剂,在醚化 H 2 O 2 中实现了空间拥挤的多功能环氧化物的过水解。得到的氢过氧化物环化得到 1,2,4-三恶烷,可以很容易地制成青蒿素和一系列新型类似物。一些具有两个这样的三恶烷部分的化合物显示出与青蒿琥酯或氯喹相当甚至更好的体外抗疟活性。
