Abstract
本发明提供了一种用于制备式(I)的曲前列尼尔及其盐的新方法,其在环系统的建造的过程中使用若干种新的中间体。
Description
本发明涉及式I的曲前列尼尔(treprostinil)及其与碱的无定形形式(amorph)、无水物(anhydrate)、一水合物(monohydrate)和多水合物(polyhydrate)盐的制备,涉及通式III、IV、V、VI、VII、VIII、IX、X、XI、XII、XIII、XIV和XV的曲前列尼尔中间体并涉及其制备。
曲前列尼尔是一种具有血小板聚集抑制和舒血管活性的合成的前列环素衍生物,其可以皮下、静脉内、吸入或口服形式施用。
其治疗领域为肺动脉高压(Pulmonary Arterial Hypertension,PAH)的治疗(Drugs,2012,72(18)2351-2363)。
对于曲前列尼尔的苯并茚结构部分的构建而言,若干方法是已知的。迄今为止描述的合成路线的概述已经公开在Drugs of the Future,2001,26(4)364-374中。
比较这些合成路线,描述在专利说明书WO99/21830 A1中的Pauson-Khand环化似乎是用于构建环系统最有效的方法。
根据专利说明书WO 99/21830 A1(US 6441245 B1)中描述的实施例,通过方案1中概述的反应路线合成苯并茚关键中间体。
方案1在描述部分的末端,实施例之前进行了展示。
然后通过如在描述部分的末端,实施例之前展示的方案2中所示的已知化学反应将关键中间体转化成曲前列尼尔。
在专利说明书WO 2009/158010 A1中,公开了氘化的曲前列尼尔衍生物的制备。
闭环通过Pauson-Khand环化进行。在该案例中,具有三键的链也由至少7个碳原子构成。由Pauson-Khand环化生成的分子已经含有曲前列尼尔侧链(方案3)。
方案3
-其中Z(1,3,4)’和Y(1,2,3)’表示氢或氘
-其中R1’是任选含有1个或多个氘的苯基。
专利说明书WO 2011/153363 A1和WO 99/21830 A1中所述的方法之间的区别如下:
含有三键的侧链与醛的偶联是在手性催化剂((+)-N-甲基麻黄碱)的存在下进行,以在一个步骤中获得手性醇而不形成外消旋醇的方式进行。以该方式,去除了一个氧化步骤和立体选择性还原。
已经降低了八羰基二钴的量(仅使用了2-15mol%而不是等摩尔比)并且闭环是在一氧化碳压力下进行。
全合成方案呈现在描述部分的末端,实施例之前的方案4中。
专利说明书WO 2012/009816 A1中描述的合成也使用了Pauson-Khand环化来形成苯并茚环。该合成中的新颖性在于酚羟基被对甲氧基苄基(PMB)保护基保护。
在该案例中,具有三键的侧链也含有至少7个碳原子。
由Pauson-Khand环化形成的分子将已经含有曲前列尼尔侧链。
全合成方案呈现在描述部分的末端,实施例之前的方案5中。
曲前列尼尔盐的合成在专利说明书WO 2009/078965(PCT/US2008/013686)(United Therapeutics)中详细地给出。其描述了结晶性二乙醇胺盐的制备。
根据该方法,经由苯并茚结构的芳族羟基的烷基化获得苯并茚腈。(方案6)
方案6
所述苯并茚腈被水解成曲前列尼尔,并且在未经分离的情况下转化成结晶性二乙醇胺盐。(方案7)
方案7
通过用酸处理从曲前列尼尔二乙醇胺盐释放曲前列尼尔。(方案8)
方案8
在分离各相之后,蒸发乙酸乙酯相,将残余物用含水乙醇结晶,经过滤收集并干燥。
通过二乙醇胺盐纯化是如此有效的,以至于无需通过色谱法纯化苯并茚腈衍生物。
可以用各种碱将高纯度曲前列尼尔转化成期望的高纯度盐。
钠盐形成的详细描述描述于专利说明书WO 2012/088607中。
根据该说明书,将苯并茚衍生物用溴乙酸甲酯烷基化,并通过使用氢氧化钾在甲醇-水溶剂混合物中的溶液将所得曲前列尼尔甲酯未经纯化地水解成曲前列尼尔。
然后将反应混合物用盐酸酸化,滤出析出的白色固体,用甲醇-水混合物洗涤,真空干燥并转化成钠盐。(方案9)
方案9
我们的目的是详述一种方法,其中下部链中的手性中心仅在合成的末尾才构造出来,并且该方法是稳健的(robust)并且具有良好的可扩展性(wellscalable)。
本发明的主题是一种用于制备式I的曲前列尼尔及其与碱的无定形形式、无水物盐以及其一水合物和多水合物的方法

本发明的另一个主题是用于制备式I的曲前列尼尔与碱的无定形形式、无水物、一水合物和多水合物盐的新颖的方法
在曲前列尼尔盐中,其中通用形式的曲前列尼尔钠盐描述于WO99/25357(UnitedTherapeutics)中,而没有用化学-物理数据来表征它们。申请人提交至EP1628654(UnitedTherapeutics)的证据1中第一次提及曲前列尼尔钠盐的熔点为56℃。
WO 2012/088607(Alphora)描述了一种用于制备曲前列尼尔钠盐的新方法,其中将曲前列尼尔溶解于与水可混溶的有机溶剂中以形成曲前列尼尔溶液,然后将该溶液与含有碱金属阳离子的水溶液反应以形成含有曲前列尼尔盐的反应混合物,使该盐结晶并收集形成的盐。
根据本发明,式I的曲前列尼尔与碱的无定形形式、无水物、一水合物和多水合物盐以如下方式制备:将曲前列尼尔溶解于极性溶剂中,将固体碱加入该溶液中,搅动反应混合物并且当盐形成完成时,将溶液过滤、浓缩,将浓缩物的溶剂交换为结晶的有机溶剂,并结晶曲前列尼尔盐。
为了制备式I的曲前列尼尔与碱的盐,作为极性溶剂,可应用C1-5开链或支链有机醇,优选乙醇;作为碱,可应用无溶剂的含有期望的盐的阳离子的有机或无机碱,例如含有碱金属阳离子或碱土金属阳离子的有机或无机碱,例如碳酸钠一水合物、碳酸氢钠或甲醇钠,优选碳酸钠的水合物。
反应混合物在惰性气氛中搅动,直到盐形成完成。
根据本发明的一个实施方案,作为结晶含水醚-、酯-或酮-型溶剂的有机溶剂,即作为醚-型溶剂,可应用开链或支链简单或混合醚,优选叔丁基甲基醚。
结晶优选在50℃-(-40℃)之间的温度进行。
作为使用含有钠阳离子的有机或无机碱的上述方法的结果,获得了白色结晶性曲前列尼尔钠盐一水合物(形式A),其为一种新化合物。
根据本发明的另一个实施方案,如果结晶的有机溶剂是不含水的醚-、酯-或酮-型溶剂,则获得无定形曲前列尼尔钠盐,其为一种新化合物。
根据本发明,曲前列尼尔钠盐无水物(形式B)可通过进行上述方法直至结晶步骤并在60-100℃或在真空中进行结晶来制备。另一种可能的方法是,将钠盐一水合物吸收在不溶解或仅微溶盐的溶剂中并在60-90℃搅拌1-6小时。作为溶剂,优选可应用己烷、庚烷、甲苯、乙酸乙酯。
如果将曲前列尼尔钠盐一水合物或无水物保持在60%水含量的气氛中达48小时或保持在空气中达5-8天,则获得新颖的曲前列尼尔钠盐多水合物(形式C)。
不同形式的DSC和X-射线粉末衍射(XRPD)谱显示于图1-9中。
这些上述盐形式显示了用于制备药物制剂的合适的稳定性和适用性。
在本发明的优选实施方案中:
炔丙基醇用甲氧基甲基基团保护。
被保护的炔丙基醇(XVII)在甲基溴化镁格氏试剂的存在下与2-烯丙基-3-甲氧基苯甲醛(XVI)反应。将由此获得的外消旋醇(XV)氧化。
例如通过Swern氧化方法或通过用铬(VI)氧化进行氧化。
酮XIV的立体选择性还原产生手性醇XIII。
立体选性还原可例如在Corey催化剂的存在下用硼烷-二甲基硫醚络合物进行。
可通过在手性碱,例如(+)-N-甲基麻黄碱和三氟甲磺酸锌的存在下使被保护的炔丙基醇(XVII)与2-烯丙基-3-甲氧基苯甲醛(XVI)反应直接制备手性醇XIII。
羟基基团用叔丁基二甲基甲硅烷基基团保护,甲硅烷基醚(XII)在八羰基二钴的存在下在Pauson-Khand反应中被环化。作为反应的结果,通过掺入CO分子形成三环(XI)。
环化可在一氧化碳气氛下使用等摩尔量的八羰基二钴或更优选使用催化量的八羰基二钴进行。
通过催化氢化移除甲硅烷基氧基基团,并且五元环的双键是饱和的。三环酮(X)的立体结构通过用碱(二氮杂二环壬烷/乙醇)异构化形成。
还原氧代基团(IX),用对苯基苯甲酰基(PPB)基团(VIII)保护所得到的仲羟基基团。
通过用酸(VII)处理裂解甲氧基甲基保护基。
将伯羟基基团氧化(VI)。
将所得到的醛VI未经分离地与膦酸2-氧代-庚酯反应。
将由此得到的烯酮V通过选择性还原方法还原,例如在Corey催化剂的存在下用硼烷-二甲基硫醚络合物。
将所得到的式IV的化合物的对苯基苯甲酰基保护基通过在碱的存在下的甲醇解移除。
通过催化氢化进行的式III的烯醇的双键的饱和产生了式II的苯并茚衍生物。
根据本发明的另一个优选的实施方案,将2-戊-4-炔氧基四氢吡喃而不是被保护的炔丙基醇用作起始原料。通过在手性催化剂的存在下与二戊基锌或戊基溴化镁反应立体选择性地构建侧链。
式II的苯并茚是曲前列尼尔的关键中间体,通过已知化学步骤将其转化为曲前列尼尔。
第一个化学步骤是甲基醚的裂解。甲基基团的移除用硫醇在卤化铝的存在下进行。
对于卤化铝,选择三氯化铝,对于硫醇,选择没有气味的十二烷基硫醇而不是常用的乙硫醇来制备三羟基衍生物。(方案10)
方案10
下一步是用卤代乙酸酯,例如溴-或氯乙酸乙基-或甲基酯烷基化芳族羟基基团。在我们的方法中,用溴乙酸乙酯烷基化三羟基衍生物。(方案11)
方案11
乙酯衍生物的水解产生结晶性曲前列尼尔。
在我们的方法中,水解用氢氧化钠水溶液在四氢呋喃中进行。
当反应完成时,将反应混合物用叔丁基甲基醚洗涤。通过加入酸水溶液将水相的pH设定为pH≤3。用叔丁基甲基醚萃取曲前列尼尔,洗涤产物溶液并蒸发。(方案12)
方案12
对于盐形成,将曲前列尼尔溶解于乙醇中并将固体碳酸钠一水合物加入其中。(方案13)。
方案13
将溶液经微孔过滤器过滤,将乙醇交换为已经用水饱和的叔丁基甲基醚并在室温结晶曲前列尼尔钠盐。
根据本发明的方法的优点在于:
·苯并茚三环的形成不需要昂贵的手性起始原料。
·侧链的构建是通过用于前列腺素化学中的具有良好的可扩展性的和稳健的化学步骤(Wittig-或改良的Wittig反应)来实现的,或通过在手性催化剂的存在下使用有机金属化合物而立体选择性地进行。
·在Wittig反应中获得的烯酮可在立体选择性反应中以良好的收率转化为期望的对映异构体。
·所应用的对苯基苯甲酰基基团(PPB-基团)是在UV中可被良好地检测的。
·所述PPB-基团提高了中间体的结晶能力并有助于它们的纯化。
