3-dioxabicyclo[3.3.1]nonan-8-ols. A variety of cyclic peroxides have been studied as potential candidates for the treatment of malaria caused by chloroquine-resistant parasites.1 Our attention has been given to yingzhaosu A (1) and to arteflene (2), two endoperoxides characterized by a 2,3-dioxabicyclo[3.3.1]nonane system as a central molecular feature (Figure 1). Yingzhaosu A was isolated from an extract of Artabotris
描述了 1,5 二烯的硫醇-氧共氧化在制备 6 元环内过氧化物中的首次应用。用PhSH、双氧和自由基引发剂处理S-(-)-柠檬烯和相关的单萜,然后选择性还原中间体氢过氧化物-内过氧化物,得到4,8-二甲基-4苯基硫甲基-2,3-二氧杂双环[3.3.1]壬聚糖-8-ols。多种环状过氧化物已被研究作为治疗由耐氯喹寄生虫引起的疟疾的潜在候选药物。 1 我们已经注意到 yingzhaosu A (1) 和 arteflene (2),这两种内过氧化物的特点是 2,3 -二氧杂双环[3.3.1]壬烷系统作为中心分子特征(图1)。
