artemisinin-like antimalarials, a series of structurally simple 3-aryl-1,2,4-trioxanes 5 was designed and was prepared in three to five operations from commercial reactants. The 3-aryl group was attached in each case as a nucleophile. In an electronically complementary fashion, 3-(fluoroalkyl)-trioxanes 6 were prepared via attachment of electrophilic fluoroalkyl esters. Both in vitro and in vivo antimalarial evaluations
基于对青蒿素样抗疟药作用机理的机械理解,设计了一系列结构简单的3-芳基-1,2,4-三氧杂环己烷5,并由商业反应物以三至五次操作制备。在每种情况下,将3-芳基作为亲核试剂连接。以电子互补的方式,通过附接亲电性氟代烷基酯来制备3-(氟代烷基)-三恶烷6。这些新的三恶烷的体外和体内抗疟药评估均显示12 gβ-甲氧基-3-芳基三恶烷5g,5j,5k和51具有很高的效力,而结晶氟苄基醚三恶烷5k甚至在口服给啮齿动物时也特别有效。如将六甲基杜瓦瓶苯重排成六甲基苯所示,
