Abstract
本發明係關於一種用於製備魯比前列酮(Lubiprostone)之新穎方法及經由該方法製得之新穎中間物。本發明方法不會產生難以移除之氫化副產物,因此能夠以高效率且低成本之方式製造魯比前列酮。
Description
本發明係關於一種用於製備魯比前列酮之新穎方法及其新穎中間物。
魯比前列酮係用於治療諸如慢性特發性便秘,主要是女性腸激躁症候群相關性便秘以及類鴉片誘發之便秘等疾病之藥品Amitiza®中的活性醫藥成分。在先前技術,諸如EP 0430551、US 7812182、US 7928252、US 8309744、US 9382272及CN 103787942中所揭示之現今用於合成魯比前列酮之方法係使用科里內酯(Corey lactone)或其衍生物作為起始物質,藉由如以下流程A中所示之二步驟威悌反應(Wittig reaction)分別建構魯比前列酮之α-側鏈及ω-側鏈。然而,科里方法需要至少8至12個合成步驟,故其產率較低。
流程A。
如以下流程B中所示,在先前技術,諸如US 9670234及WO 2012048447中所揭示之方法係藉由使環戊烯酮A與乙烯基硼化合物或乙烯基銅酸鹽B進行1,4-共軛加成,以形成在C13-C14、C5-C6及/或C17-C18處具有雙鍵的魯比前列酮之中間物C;經由氫化移除苯甲基保護基,並將C13-C14、C5-C6及/或C17-C18處之雙鍵還原成單鍵以得到化合物D;及再進行另外三個化學反應來合成魯比前列酮。
流程B。
此方法可以較快速地形成魯比前列酮。然而,由於在化合物C13-C14處之雙鍵兩側的位阻極大,使得中間物C極難被氫化或還原,因而必須在高壓及高溫下使用大量昂貴的氫化催化劑,才能將所有的雙鍵還原成單鍵。在此情況下,由於不完全的雙鍵還原將必然產生副產物,且因極端條件亦將產生脫水或脫氧副產物,或甚至是具有移位之雙鍵的副產物。由於這些副產物之極性與具有單鍵的主要產物非常相近,幾乎不可能使用矽膠層析法完全地移除氫化副產物,故此方法在工業量產製造魯比前列酮之純化上面臨著極大困難。
因此,目前亟需要一種能夠以高效率且低成本之方式製備高產率及高純度之魯比前列酮的方法。
在一方面中,本發明提供一種用於製備魯比前列酮之新穎方法,其可以有效地解決前述習知問題。

化合物之ω-側鏈中的P2
保護基的脫保護反應。用於進行脫保護反應之條件與P2
的選擇有關且係熟習此項技術者可輕易瞭解者。舉例而言,當P1
為對酸敏感之保護基,諸如四氫呋喃基,且P2
係三烷基矽烷基時,該三烷基矽烷基保護基可以在中性或鹼性條件下,藉由使用氟離子,諸如氟化四丁基銨來選擇性地移除。
流程C之步驟c係關於氧化反應。在適當氧化條件,諸如柯林斯氧化(Collins oxidation)、斯溫氧化(Swern oxidation)、氯鉻酸吡啶鎓鹽(PCC)氧化、重鉻酸吡啶鎓鹽(PDC)氧化及四甲基哌啶氧化物(TEMPO)氧化,較佳地在TEMPO氧化下,使用TEMPO氧化法,將式4
化合物中之C15-OH氧化成酮基,以形成式5
之二酮。
流程C之步驟d及步驟e分別關於移除P1
保護基及移除R1
基團,且該兩個步驟之順序可互換。
如流程C之步驟d所示,式5
或6a
之化合物經受脫保護反應以移除P1
保護基。用於進行脫保護反應之條件與P1
的選擇有關且係熟習此項技術者可輕易瞭解者。舉例而言,當P1
係四氫哌喃基時,可以將式5
或6a
之化合物溶解於適合溶劑,諸如甲醇或體積比為約5比1之丙酮與水的溶劑混合物中,再以脫保護劑,諸如氯化氫、對甲苯磺酸或對甲苯磺酸吡啶處理,並在室溫下攪拌約10分鐘至約10小時;接著可以用鹼,例如氫氧化銨淬滅反應混合物,再以習知方式進行處理程序。當P1
為未經取代或經取代之苯甲基時,可以在適合溶劑中並在氫氣存在下,藉由使用氫化催化劑實現脫保護反應。適合的氫化催化劑包含選自由以下組成之群的金屬:鈀、鉑、銠、鎳及其混合物。催化劑之實例包括(但不限於)Pd/C、Pt/C及Ni。適合的溶劑可選自四氫呋喃、乙酸乙酯、甲醇、乙醇、甲苯及其混合物。
如流程C之步驟e中所示,使式5
或6b
之化合物經受水解反應以移除R1
基團。用於進行水解反應之條件與R1
的選擇有關且係熟習此項技術者所能輕易瞭解者。舉例言之,當R1
係烷基時,式5
或6b
之化合物可以在水相(水或緩衝液),及/或有機溶劑諸如己烷、甲苯、四氫呋喃、甲基異丁基酮及其混合物中,在酶,較佳地為假絲酵母南極脂肪酶(Candida antarctica lipase),諸如脂肪酶435存在下經受酶水解反應。當R1
為未經取代或經取代之苯甲基時,式5
或6b
之化合物可以經受氫化反應,該氫化反應係在氫化催化劑存在下於適合溶劑中與氫氣進行反應。
相較於習知魯比前列酮的合成方法,本發明之新穎方法僅需要較少的步驟。意外地,本發明之新穎方法亦可以較高產率、較高純度及較低成本製得產物。詳細言之,在前述流程B之習知方法中須使用大量昂貴的氫化催化劑;然而,在本發明之新穎方法中,僅須在流程C之步驟d或e中使用少量的氫化催化劑,就可以迅速地移除如苯甲基之保護基。此外,本發明之新穎方法可以完全避免在流程B之習知方法中產生的副產物,故可有效地解決習知方法所造成的缺點。 新穎的式 3 化合物
本發明亦關於一種新穎的式3化合物:
其中P1
及P2
獨立地為羥基保護基,且R1
係C1 - 7
烷基、芳基或芳烷基,其各自未經取代或經C1 - 4
烷基、硝基、鹵素或烷氧基取代。 新穎的式 2 化合物
