Synthesis of β-sulfenyl endoperoxides 9 was achieved by a four component sequential free radical reaction based on the application of the thiol-olefin-co-oxygenation reaction to monoterpenes, followed by in situ treatment with triphenylphosphine. β-Sulfenyl endoperoxides 9 were oxidized with m-CPBA to β-sulfonyl endoperoxides 10. This process provides an efficient method for the preparation of peroxides
β-亚砜基内过氧化物9的合成是基于四组分顺序自由基反应,该反应基于将硫醇-烯烃-共加氧反应应用于单萜,然后用三苯基膦进行原位处理。β-硫基内过氧化物9与被氧化米-CPBA到β-磺酰内过氧化物10。该方法提供了一种有效的方法,用于制备含有2号3-二氧杂双环[3.3.1]壬烷体系(2)的过氧化物,该体系具有应召素A(3)系列抗疟剂的特征。描述了一种用于鉴定立体异构体的简单NMR诊断工具。
