Co(II)-catalyzed peroxidation of dienes including (S)-limonene in the presence of molecular oxygen and triethylsilane provided in each case the corresponding 2,3-dioxabicyclo[3.3.1]nonane derivatives via the intramolecular cyclization of the unsaturated peroxy radical intermediates. The product composition was remarkably influenced by the structure of the dienes, the nature of the solvents, and the
在分子氧和三乙基硅烷存在下,Co(II)催化的二烯(包括(S)-柠檬烯)的过氧化,通过不饱和过氧自由基的分子内环化作用提供了相应的2,3-二氧杂双环[3.3.1]壬烷衍生物中间体。产物的组成显着地受到二烯的结构,溶剂的性质以及底物和催化剂的浓度的影响。在这项研究中获得的一些yingzhaosu A类似物在体外显示出显着的抗疟活性。
