技术领域
本发明涉及一种新恶唑烷酮类抗菌素泰地唑胺或其磷酸盐的制备方法及其中间体化合物。
背景技术
磷酸泰地唑胺,对包括革兰氏阳性菌如葡萄球菌、肠道球菌和链球菌,厌氧微生物如类菌体和梭菌体以及耐酸微生物如结核分支菌、鸟分支菌在内的人和动物病原体的有力抗菌活性。由Cubist Pharmaceuticals公司(Merck公司的子公司)和拜耳共同开发tedizolid(以前称为torezolid),最初由Dong-A Pharmaceutical东亚制药(东亚ST)发现抗菌药物前体,用于对革兰氏阳性菌感染的治疗,Tedizolid在血浆中迅速转化成其活性形式,TR 700(DA 7157)。
WO2005058886A1)公开了3-[3-氟-4-[6-(2-甲基-2H-四唑-5-基)-3-吡啶基]苯基]-5-(羟基甲基)-2-恶唑烷酮的合成使用3-氟苯胺为原料,经过Cbz保护,再与缩水甘油丁酸酯反应得到化合物3,碘代后再制备成锡试剂5,之后与5-溴-2-(2-甲基-2H-四唑-5-基)-吡啶suzuki偶联得到关键中间体K。反应式如下:
该原研东亚制药化合物专利路线步骤较长,总收率不高。成本方面,需要使用比较昂贵的试剂如CF3COOAg,而且路线中两次使用Pd催化剂分别制备中间体5和K,条件苛刻不易于放大生产。
后来原研许可商Trius Therapeutics公司对原研化合物路线进行改进,其专利WO2010042887采用以4-溴-3-氟苯胺为起始原料,合成硼酸酯10,再与5-溴-2-(2-甲基-2H-四唑-5-基)-吡啶进行suzuki偶联生成中间体11,然后在与缩水甘油丁酸酯反应生成噁唑烷酮中间体K,具体路线如下所示():
该路线相比化合物制备方法步骤短,总收率有所提高,但反应条件比较苛刻,需要使用丁基锂并在超低温(-65℃)下进行;n-BuLi和LiHMDS的使用需要严格的无水条件。
另外CN104496979A公开了一种制备泰地唑胺的方法,如下反应式所示:
其中,R为氢或羟基保护基;L和R1中一个为离去基团,另一个为BF3或BR2R3,其中R2和R3独立的选自由OH和任意取代的C1-C6一元和二元醇组成的组,其中R2和R3在一起可以成环;该路线采用Pd催化合成硼酸酯中间体II,分离纯化出硼酸酯II后,再与化合物I在Pd催化条件下进行suzuki偶联得到式H所示化合物。路线中须分离出II,再进行suzuki偶联,操作繁琐。
目前关于泰地唑胺中间体的现有方法,均操作复杂,反应时间长,总收率低,纯度较低。
