技术领域
本发明涉及有机化学合成领域,具体涉及到一种亚砜还原合成硫醚的技术。
背景技术
含硫化合物主要包括以下几类结构:磺胺类、硫醚类、亚砜类、青霉素类及其衍生物等。含硫化合物往往表现出不同的生物活性,在医药工业中具有重要的应用价值,硫醚类化合物广泛存在于天然产物、药物和材料中,硫醚用途较广,例如用作农药、燃料油添加剂和润滑油添加剂等。近年来,人们探索了许多合成硫醚类化合物的优良方法。其中,亚砜还原是最常用的转化方法。目前由亚砜合成硫醚类化合物的方法主要有以下几种:(1)催化加氢,通常使用贵金属催化剂,同时使用到高压设备,且反应条件十分苛刻。(2)利用还原氢化物试剂,如硅氢化物、硫氢化物等,而利用这些试剂的还原反应多会产生副产物。(3)脱氧还原,使用强亲电试剂(三苯基磷和草酰氯)激活亚砜的还原,这种方法有着底物适应性差的缺点。
四羟基二硼近年来被证实为一种高效优良的还原试剂,廉价易得、环境友好。本专利以简单易得的甲苯为溶剂,在无金属催化条件下,通过四羟基二硼介导的还原反应实现了多种亚砜化合物的还原。反应条件简单,环境友好,底物适应性广,产率高,同时该反应也非常稳定,适宜于工厂放大。
