Description
技术领域
本发明属于化学制药领域,具体涉及一种奥沙利铂的合成方法。
背景技术
奥沙利铂是铂原子与1,2二氨环己烷(DACH)及一个草酸基结合的顺式-草酸(反式-1-1-1,2-DACH)铂(C8H14N2O4Pt),单一对映结构体,一种抗结肠癌药物,最早是1997年在法国批准上市,目前已在多个地区或国家获批用于临床。奥沙利铂还于2003年底和2004年4月先后在欧美获得了用作结直肠癌一线疗法的新适应证,而此无疑将大大加速刺激其市场扩展能力,使其2004年的全球总销售额超越12亿美元,此外,联用方案还已完成用作结肠癌术后辅助疗法的大型研究并被证实具有较单用氟尿嘧啶-亚叶酸显著减少患者疾病复发风险的临床益处,由此先后在欧美获得了用作Ⅲ期结肠癌患者辅助疗法的第三种适应症。该药在全球的销售额逐年增长,因此对于奥沙利铂的合成一直受到广泛的关注。目前已有不少关于奥沙利铂的合成方法的报道,但是有些存在收率低、反应时间过长等等问题。
发明内容
本发明目的在于提供一种奥沙利铂的合成方法,采用微波合成方法,操作简便、反应温和、成本低、收率高。
为实现上述目的,本发明的技术方案是:(1)以氯亚铂酸钾(K2PtCl4)与(1R,2R)-1,2-环己二胺在水中微波条件下反应生成顺式-二氯(1R,2R)-1,2-环己二胺铂;(2)顺式-二氯(1R,2R)-1,2-环己二胺铂先后与硫酸银、四乙基碘化铵、草酸、氢氧化钡在微波条件下合成奥沙利铂。
一种奥沙利铂的合成方法,包括如下步骤:
(1)取摩尔比为1:1.05-1.10的氯亚铂酸钾(K2PtCl4)与(1R,2R)-1,2-环己二胺于水(溶剂)中,避光,在温度为35℃--45℃、功率为200W-500W的微波条件下反应2-2.5h,生成顺式-二氯(1R,2R)-1,2-环己二胺铂;
(2)将步骤(1)所得顺式-二氯(1R,2R)-1,2-环己二胺铂充分溶于水中,然后添加硫酸银,所述的顺式-二氯(1R,2R)-1,2-环己二胺铂与硫酸银的摩尔比为1:2.03-2.09,避光,在温度为35℃-50℃、功率为200W-400W的微波条件下,搅拌反应4h-4.5h,过滤;
(3)取步骤(2)滤液中加入四乙基碘化铵,四乙基碘化铵与顺式-二氯(1R,2R)-1,2-环己二胺铂的摩尔比为0.3-1,2:1,搅拌0.5h-1h,加入活性炭,搅拌过滤;
(4)取步骤(3)滤液搅拌过程中先后加入草酸和Ba(OH)2·8H2O,其中草酸与顺式-二氯(1R,2R)-1,2-环己二胺铂的摩尔比为0.45-1.23:1,Ba(OH)2·8H2O与硫酸银的摩尔比为0.2-0.57:1,避光搅拌2h-3h,过滤,滤液蒸干得白色固体,后精制得奥沙利铂产品。
上述的白色固体用冷水、丙酮进行洗涤干燥得到奥沙利铂产品。
本发明的合成路线为:
与现有技术相比,本发明的优点是:利用微波反应条件,大大提高生产各种原料药的效率,有效的缩短了反应时间,从而缩短生产周期,提高收率,降低了生产成本。另外,采取用四乙基碘化铵,来除掉过量银离子,并用活性炭进行脱色,使得产品纯度较高。后期采用草酸和Ba(OH)2·8H2O,反应时间短,条件温和,且收率较高。
