技术领域
本发明属于合成化学领域,具体涉及一种可见光催化手段制备3-三氟烷基喹喔啉酮化合物的方法。
背景技术
三氟烷基团可以显著地改变化合物的物理、化学性质,提升其生理性质, 比如亲脂性、代谢稳定性、与靶标蛋白结合能力、细胞膜穿透性和生物可利用度。喹唑啉酮作为一种重要的杂环化合物骨架广泛存在于生物活性分子和药物分子中,在药物化学方面得到十分广泛的应用。研究表明,喹唑啉酮类化合物经三氟烷基修饰后,展示出较强的生物活性如抗菌、抗肿瘤、抗HIV、消炎等(Eur. J. Med. Chem. 2014, 80, 383;ACS Med. Chem.Lett. 2012, 3, 1034;J. Med. Chem. 2011, 54, 5747;Mini-Rev. Med. Chem. 2006,6, 1179)。近年来,喹喔啉酮 C(3)位的直接三氟甲基化反应和三氟乙基化反应构建3-三氟甲基喹喔啉酮和3-三氟乙基喹喔啉酮方面取得了一些的进展(Adv. Synth. Catal. 2018,360, 3969; Asian J. Org. Chem. 2019, 8, 887;Adv. Synth. Catal. 2019, 361,5490;Asian J. Org. Chem. 2019, 8, 1942; Org. Lett. 2018, 20, 5497.)。然而,更加复杂多样性的3-三氟烷基喹喔啉酮制备的方法报道较少且遭受一定的局限性。
2019年,Studer小组报道了3当量强碱DBU(1,8-二氮杂双环[5.4.0]十一碳-7-烯)介导下可见光促进的喹喔啉酮、1-己烯和三氟碘甲烷(气体)三组分反应合成一例3-三氟烷基取代的喹喔啉酮化合物的方法 (反应式1)。该反应需要气体三氟碘甲烷试剂为原料,同时反应需要惰性气体氩气保护,操作复杂繁琐(Org. Lett. 2019, 21, 325)。
(反应式1)
最近,Wei和Li课题组分别采用3当量过二硫酸钾和3当量醋酸碘苯的介导喹喔啉酮、烯烃和三氟甲基亚磺酸钠(固体)三组分反应制备多种3-三氟烷基取代的喹喔啉酮化合物(J.Org. Chem. 2020, 85, 6888; Tetrahedron 2020, 76, 131199)(反应式2)。这两种方法采用了固体三氟甲基亚磺酸钠代替了气体三氟碘甲烷,操作简便,但反应的局限性在于需要加热和加入大量的无机氧化剂,反应后留有残留物对环境产生污染,不利用工业化生产。
(反应式2)
