Description
技术领域
本发明涉及有机合成的技术领域,尤其涉及一种3,5-二羟基戊苯的制备方法。
背景技术
3,5-二羟基烷基苯是一类很受人们关注的天然化合物,广泛存在于腰果漆树科、山龙眼科、禾本科等植物中。这类化合物具有多种生物学活性,可杀灭多种病原体的真菌和细菌。其中的3,5-二羟基戊苯(Olivetol),俗称5-戊基间苯二酚,是一种重要的医药中间体,早期是采用降解地衣植物经提取得到地衣酸,而后制得3,5-二羟基戊苯,但收率很低。
20世纪80年代,科学家发现3,5-二羟基戊苯可以抑制人体免疫系统方面的疾病,故其在医药领域得到了迅猛发展,从而被广泛应用。此外,3,5-二羟基戊苯还可与其他一些抗人体免疫功能低下的药物联合入药进而合成治疗艾滋病、恶性肿瘤的药物,用于综合抑制和治疗由逆转录酶病毒引起的人体免疫功能缺乏症、癌症和其他恶性肿瘤等,具有显著的效果。
目前,3,5-二羟基戊苯主要有以下几种合成方法:
(1)、Miroslav Sisa等人以3,5-二甲氧基戊苯为原料,低温条件下逐滴加入三溴化硼,反应结束后经猝火、碳酸氢钠中和、二氯甲烷萃取,再水洗、硫酸镁干燥、真空浓缩、柱层析后得到3,5-二羟基戊苯。
(2)、WA Ayer等人以3,5-二甲氧基苯甲酸为原料,与碳酰氯反应生成3,5-二甲氧基苯甲酰氯,然后在甲苯、醋酸钠、钯/碳催化剂以及氢气的体系下转化生成3,5-二甲氧基苯甲醛;接着,3,5-二甲氧基苯甲醛在格式试剂、氢化硫酸、钯/碳催化剂的作用下生成3,5-二甲氧基苯甲醚;最后,将3,5-二甲氧基苯甲醚和NaI用MeCN溶解混合,并在氮气条件下边搅拌边加入ClSiMe3,加热回流36小时后,用水猝灭、乙醚萃取,10%Na2S2O3洗去碘和盐水后干燥、浓缩即得3,5-二羟基戊苯。
(3)、中国专利CN109928867以苯为原料,通过路易斯酸的酰基化反应得到苯戊酮,再经硝化、羰基还原、硝基还原后得到3,5-二氨基戊苯,最后通过重氮化反应制得3,5-二羟基戊苯。
Miroslav Sisa等人在使用3,5-二甲氧基戊苯为原料的合成方法中,其原料很难得到;而WA Ayer等人使用3,5-二甲氧基苯甲酸为原料的合成方法,工艺路线比较繁琐且产率不高。国内使用苯为原料的合成方法中,硝化反应的硝化剂需由发烟硫酸和硫酸配置而成,实验存在较大危险性。
随着国内外对3,5-二羟基戊苯的需求量不断增大,开发新的工艺简单、原料易得的合成工艺路线就变得尤为重要。
