The novel heterocycle 3-oxatetracyclo[5.3.1.15,9.02,5]dodecane 4 is prepared by a simple and effective method, involving synthesis of the corresponding 2-hydroxy-1-adamantanomethanol followed by its intramolecular cyclization with thionyl chloride, along with 4-oxo-adamantane-3,5,4-dioxathiane 5 in yields depending on the reaction temperature. Dioxathiane 5 was markedly active against vesicular stomatitis
新颖的杂环3-氧杂四环[5.3.1.1 5,9 0.0 2,5 ]十二烷4是通过一个简单而有效的方法制备,涉及相应的2-羟基-1- adamantanomethanol的合成,随后其分子内环化与亚硫酰氯取决于反应温度,其产率与4-氧代金刚烷-3,5,4-二氧杂环丁烷5的产率有关。Dioxathiane 5对水疱性口炎病毒具有显着活性,其效力比(S)-9-(2,3-二羟丙基)腺嘌呤高2.5倍。NMR数据和有关亚硫酸盐5和相应的二恶烷6的理论计算表明,SO是赤道取向的。
