highly hindered quaternary C-12a in an advanced qinghaosu (artemisinin) precursor has been achieved through a facile perhydrolysis of a spiro epoxy ring with the aid of a previously unknown molybdenum species without involving any special equipment or complicated operations. The resultant β-hydroxyhydroperoxide can be further elaborated into qinghaosu, illustrating an entry fundamentally different from
H 2 O 2在高级青蒿素(青蒿素)前体中的高度受阻四级C-12a上的附着已通过螺环环氧环的容易的过水解,借助先前未知的钼物种而实现,而无需任何特殊设备或复杂操作操作。所得的β-羟基氢过氧化物可以进一步修饰成轻质素,说明从根本上不同于现有的这种杰出的天然产物对疟疾化疗具有重要意义。
