Description

一种羟基取代的菲类衍生物的合成方法
技术领域
本发明属于有机合成技术领域,涉及一种羟基取代的菲类衍生物的合成方法。
背景技术
羟基取代的菲类衍生物是一类重要的多环芳烃化合物,广泛存在于天然物质中,具有重要的生物、药物活性。同时,作为一类有机合成中间体,菲类化合物在有机合成化学、药物化学、材料化学、电化学等领域都有广泛的应用价值。 目前,羟基取代的菲类衍生物的合成方法主要有以下两种:1)先通过二氯亚砜氯化,然后在三氯化铝的催化作用下发生傅克酰基化反应;2)以甲基磺酸作为催化剂进行催化反应。然而,这些合成方法的底物普适性非常有限,仅适用于个别9-羟基菲化合物的合成,且产率不高(Organic Letters, 2006,8, 3951-3954)。而且,使用甲基磺酸催化,通常需要加入大大过量的甲基磺酸才能促进反应的顺利进行,且在反应过程中易生成醚类、甲磺酸酯类副产物。因此,开发一种普适性好、原料简单易得、反应收率高、反应时间短、操作简单、反应条件温和的合成路线,用于合成羟基取代的菲类衍生物,具有很好的实用价值。
