Abstract
本发明公开了一种3‑取代的磷酰化喹啉酮衍生物,结构如下所示:
Description
技术领域
本发明属于有机合成技术领域,具体地说,涉及一种3-取代的磷酰化喹啉酮衍生物及制备方法与应用。
背景技术
喹啉酮化合物是一类具有多种生物特性的有机小分子,在医药工业和材料科学中发挥着重要作用。喹诺沙林酮类化合物是制药工业中常用的组成成分,广泛存在于抗菌、抗病毒、抗癌、抗糖尿病、抗炎等生物活性化合物中,为此修饰喹啉酮化合物引起了化学家们极大的兴趣。喹啉酮化合物具有一定的可修饰性,其3号位可以通过引入不同的取代基实现喹啉酮的官能团化,进一步实现喹啉酮化合物在医药中间体上的应用。
近年来,化学家们实现了活化喹啉酮3-C的一些活化方法,但均需要传统的化学氧化剂或过渡金属的参与,一定程度上增加了对环境的负担,并且对实现喹啉酮化合物的工业化生产提高了经济成本,阻碍了喹啉酮化合物的大规模生产。
2017年,Yuan小组等人报道了亚硝酸叔丁酯作为氧化剂,以三氟甲磺酸作为溶剂的条件下,喹啉酮类化合物与苯胺发生的自由基反应在喹啉酮的3号位引入芳基类取代基,生成一系列的3-取代的芳基类喹啉酮衍生物(Adv.Synth.Catal.,2017,359,4197–4207)。
同年,Wang课题组报道了一种以硝酸银作为催化剂,过硫酸钾作为氧化剂,乙腈作为溶剂,在100℃的条件下反应3个小时,对喹啉酮化合物的三号位进行活化的方法,引入一系列的酰基官能团(Org.Biomol.Chem.,2017,15,8929–8935)。
2019年,Zhang课题组报道了以双(三氟乙酸)碘苯作为氧化剂,利用三氟乙醇,对喹啉酮类化合物的3号位引入三氟乙基,合成了一系列的3-取代的三氟乙基类喹啉酮衍生物(Org.Lett.2019,21,4698-4702)。
综上所述,在目前报道的活化3-取代喹啉酮衍生物的文献中,或是使用过渡金属催化剂,或是使用传统的氧化剂参与反应,不仅降低了反应成本,而且对环境造成了负担。因此,发明一种无氧化剂、无金属活化喹啉酮三号位的绿色化学手段显得尤为重要。
