一种由二甲基亚砜合成茚酮衍生物的方法
技术领域
本发明属于有机合成领域,涉及一种由二甲基亚砜(DMSO)合成茚酮衍生物的方法。
技术背景
茚酮衍生物是有机合成领域中一种重要的合成中间体。许多天然化合物和药物的结构中也具有该片段,这一特殊的结构使其具有较好的生物活性和药理作用。因此,二羰基茚酮衍生物的合成是有机合成中的重要课题。目前已报道的合成方法中使用的方法主要有如下几种:
文献1(Anna Maria Zawisza,et al.Heck-type reactions of allylicalcohols:Part IV:(2-Substituted)-1-indanones via,5-endo-trig,cyclizations[J].Journal of Molecular Catalysis A Chemical,2008,283(s 1–2):140-145.)使用烯烃醇为原料,在弱碱条件下,以醋酸钯合奎宁衍生物辛可宁为催化剂,在DMF溶剂中合成茚酮衍生物。该方法所用原料需要自制,也具有较广的底物适用性,其反应式如下:
文献2(Brown D S,et al.Epoxidation with dioxiranes derived from 2-fluoro-2-substituted-1-tetralones and-1-indanones[J].ChemInform,1995,51(33):3587-3606.)使用茚酮作为原料,钠氢作为催化剂,在THF溶剂中与碳酸二乙酯反应合成茚酮衍生物。该方法原料易得,经济实惠,其反应式如下:
文献3(Sartori G,et al.ChemInform Abstract:Selective Synthesis of 1-Indanones via Tandem Knoevenagel Condensation-Cycloalkylation ofβ-DicarbonylCompounds and Aldehydes.[J].ChemInform,1996,27(9):12179-12192.)使用苯乙酰乙酸乙酯为原料,路易斯酸催化下,与甲醛反应,硝基乙烷为溶剂,合成茚酮衍生物。其反应式如下:
以上方法中有的使用的原料昂贵难得,有的反应条件苛刻,有的采用毒性较大的甲醛,有的反应步骤较复杂。因此,减少反应成本,避免使用对环境影响较大的试剂参与反应,有着非常重要的现实意义。
发明内容
本发明的目的在于提供一种工艺合理、低毒性、产品质量好的由DMSO合成茚酮衍生物的方法。
实现本发明目的的技术方案是:
一种由DMSO合成茚酮衍生物的方法,反应式为:
步骤如下:以苯乙酰乙酸乙酯和二甲基亚砜为原料,在三氟甲磺酸亚铜(CuOTf)的催化下,以过量的DMSO为溶剂,在80~120℃下反应8~24h,反应结束后,反应液经分离纯化得到2-乙氧基甲酰基-1-茚酮。
所述的苯乙酰乙酸乙酯和DMSO的摩尔比为1:20~1:30,优选为1:25~1:30。
所述的催化剂三氟甲磺酸亚铜用量为苯乙酰乙酸乙酯摩尔量的1~2.5倍,优选为1~2倍。
所述的反应温度优选为100~120℃。
所述的反应时间优选为8~12h。
所述的反应液经分离纯化方法为:反应结束后,反应液加入乙酸乙酯稀释,饱和食盐水洗涤3次,分离取有机层,经无水硫酸钠干燥后减压蒸馏除去溶剂,得到粗产物,粗产物经由以乙酸乙酯和石油醚的体积比为6:1的洗脱剂柱层析分离得到2-乙氧基甲酰基-1-茚酮。
与现有技术相比,本发明的显著优点是:
(1)工艺条件合理,操作简单安全,原料便宜易得;
(2)三废少,环境友好;
(3)利用DMSO作为碳源,是DMSO的新应用。
