Description
技术领域
本发明涉及一种噁唑烷酮类抗菌药物的制备方法,属于医药领域。
背景技术
细菌接触抗菌药物可发生变异而获得耐药性,而人类对抗生素的滥用更加剧了耐药菌的发展,抗生素的抗菌效果不断下降,严重威胁到人类健康,2011年世界卫生组织警告世界将进入“后抗生素时代”,各国已经意识到研发新型抗菌药物的重要性,美国于2012年批准了《FDA安全与创新法案》,其第八部分即为《鼓励开发抗生素法案》(GAIN法案)。
进入新世纪以来,新型的噁唑烷酮类抗菌药物逐渐被开发出来,代表性的如美国法玛西亚普强公司开发的利奈唑胺,该药于2000年经FDA批准在美国上市,这是全球首个上市的噁唑烷酮类抗菌药物。之后,美国Cubist公司开发的磷酸泰地唑胺也于2014年经FDA批准在美国上市。
CN103936763A公开了一种新型噁唑烷酮类抗菌药物,化合物结构如式I所示:
其中,M为H或碱金属、碱土金属、碱性氨基酸可药用盐类。
研究结果显示,式I的新型噁唑烷酮类抗菌药物具有较同类药物更强的抗菌活性,尤其是抗多耐药菌活性。
杨玉社等(“Solubility-Driven Optimization of(Pyridin-3-yl)Benzoxazinyloxazolidinones Leading to a Promising Antibacterial Agent”;Journal of Medicinal Chemistry,2013,56,)报道了式I的新型噁唑烷酮类抗菌药物的合成方法,最后通过钯碳催化氢化脱苄基还原得到式I的抗菌药物,反应路线如下:
该方法涉及氢气还原反应存在一定的缺陷,磷酸三酯(式II化合物)脱苄基反应,经过液相检测存在两个主要副产物,含量在5~10%左右,有可能是脱苄不完全或者噁唑烷酮开环产生的,该杂质后处理难以除去,影响产品的质量。另外催化剂钯碳原料成本高,最终产品中金属钯残留不易控制,不适合工业化生产。
发明内容
为克服现有技术中存在的上述缺陷,本发明提供了一种噁唑烷酮类抗菌药物的制备方法,。
本发明是通过以下方法实现的:
一种噁唑烷酮类抗菌药物的合成方法,将磷酸三酯(式II化合物)和酸在质子酸催化剂或Lewis酸催化剂存在下混合反应,液相色谱检测反应完全。反应液浓缩后用N,N-二甲基甲酰胺溶解,减压浓缩,析出固体,干燥得目标产物(式I化合物)。
反应方程式如下:
本发明用质子酸催化剂或Lewis酸催化剂作为脱苄基的催化剂,以较高的效率制备了噁唑烷酮类抗菌药物。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的质子酸催化剂选自无机酸、有机羧酸和/或有机磺酸。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的无机酸选自盐酸、硫酸、磷酸和/或固体超强酸。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的固体超强酸催化剂包括但不限于SO4 2-/TiO2和/或SO4 2-/ZrO2。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的有机羧酸催化剂包括但不限于甲酸、乙酸、丙酸、苯甲酸、柠檬酸、马来酸、富马酸、氯乙酸、三氯乙酸和/或三氟乙酸。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的有机磺酸催化剂包括但不限于甲磺酸、苯磺酸和/或对甲苯磺酸。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的Lewis酸催化剂包括但不限于三氯化铁、四氯化钛、氯化亚锡、氯化锌、氯化铝和/或三氟化硼。
本发明所述的噁唑烷酮类抗菌药物的制备方法,反应可以不加溶剂或使用水和有机溶剂的一种或组合。
本发明所述的噁唑烷酮类抗菌药物的制备方法,所述的有机溶剂包括但不限于甲苯、二氯甲烷、氯仿、四氢呋喃、丙酮、甲基异丁基酮、甲醇、乙醇、正丙醇、异丙醇和/或叔丁醇。
本发明的有益效果如下:
本发明采用的酸催化脱苄基方法,两个副产物均可以控制在3%以下,尤其采用三氟乙酸或固体超强酸(SO4 2-/TiO2、SO4 2-/ZrO2)为催化剂时,两个副产物均可以控制在0.5%以下,通过N,N-二甲基甲酰胺重结晶纯化,可以进一步降低到0.1%以下,从而符合药用要求。而且催化剂三氟乙酸及固体超强酸分别可以通过蒸馏或过滤后循环套用,工艺绿色环保。
本发明所述制备方法原料价廉易得,操作安全简便,产品质量高,收率高,容易控制杂质含量,产品的金属残留易控,适合商业化生产。
