Description

一种将甲硫基亚甲基氧衍生物转化为羟基化合物的绿色方法
技术领域
本发明属于绿色化学和有机合成技术领域,具体涉及一种将甲硫基亚甲基氧衍生物转化为羟基化合物的绿色方法。
背景技术
羟基广泛存在于多种生物活性成分中,如核苷、糖类、甾体、大环内酯类化合物、某些氨基酸侧链等。对这些活性分子进行氧化、酰化、卤化等反应时,往往需要对羟基进行保护。甲硫基亚甲基氧基团因其在酸碱条件下稳定性好而成为一种重要的羟基保护基团。
目前,关于甲硫基亚甲基氧衍生物的脱保护方法,通常需要苛刻的反应条件。脱保护过程复杂、反应时间长、稳定性差、对环境不友好,过渡金属催化剂的使用也带来了严重的环境问题,随着对环境问题的日益关注,有毒有害氧化剂的使用将被逐渐淘汰。
因此,开发一种绿色、高效、易于操作且普遍适用的甲硫基亚甲基氧脱保护成羟基化合物的方法具有重要意义。
发明内容
本发明的目的是,开发一种将甲硫基亚甲基氧衍生物转化为羟基化合物的通用、绿色的方法。
本发明采用的技术方案为:
在室温条件下,以CeBr3作催化剂,H2O2作唯一氧化剂,短时间内完成甲硫基亚甲基氧衍生物转化为羟基化合物的反应。
反应以甲硫基亚甲基氧衍生物为原料,所述衍生物的结构如式I所示:
反应于溶剂中进行,所用溶剂可为乙腈、乙醇、四氢呋喃等。
反应在催化剂条件下进行,所用催化剂为CeBr3、Ce(NO3)3-KBr、CeCl3-KBr、Ce(NH4)2(NO3)6-KBr、Ce(OTf)3-KBr、Ce(OAc)3-KBr等金属和溴化物的组合中的任意一种。
具体操作时,提供一种方案:将甲硫基亚甲基氧衍生物加入到乙腈中,两者混匀后加入催化剂CeBr3(0.01-0.1eq)搅拌均匀,然后向混合物中加入H2O2水溶液(30%,1-2eq)。反应混合物在室温下继续搅拌反应10-30min。反应完成后用稀释的Na2S2O3溶液(0.1M)淬灭,淬灭后用乙酸乙酯萃取。收集有机相,水相用乙酸乙酯萃取2-3次。合并有机相后依次用水洗,无水硫酸钠干燥,过滤,减压浓缩,即可得产物。
本发明的有益效果:
本发明与现有技术相比具有以下优点和效果:
本发明首次实现了以CeBr3催化甲硫基亚甲基氧衍生物转化为羟基化合物的反应,是一种可放大的脱除羟基保护基的绿色方法。该方法具有原料易得、成本低、反应快、底物适用范围广、路线简单、容易操作、对环境友好等特点,比之前所有的方法更具优势,具有良好的应用前景。有望在有机合成和精细化工以及制药行业中得到广泛应用。
