一種新型大環(huán)環(huán)肽化合物的合成方法與流程

本發(fā)明涉及一類從線性肽前體出發(fā),制備一種新型苯環(huán)支撐的環(huán)肽化合物的合成方法,屬于金屬催化應(yīng)用技術(shù)領(lǐng)域。



背景技術(shù):

大環(huán)化反應(yīng)是自然界將簡(jiǎn)單線性前體化合物構(gòu)建為復(fù)雜環(huán)狀化合物的一種重要方法。在具有大環(huán)結(jié)構(gòu)的天然產(chǎn)物中,大環(huán)環(huán)肽化合物在結(jié)構(gòu)上更加靈活多變,往往表現(xiàn)出很好的生物活性。與小分子藥物相比,環(huán)肽通常具有較大的體積以及表面積,這使得它們有希望應(yīng)用于更具有挑戰(zhàn)性的生物目標(biāo),如蛋白質(zhì)-蛋白質(zhì)相互作用,根據(jù)lipinski規(guī)則,這類生物活性的調(diào)節(jié)很難通過小分子藥物來(lái)實(shí)現(xiàn)。然而,與小分子化合物成熟多樣的合成方法相比,用于構(gòu)建具有特定三維結(jié)構(gòu)及藥物特性的大環(huán)環(huán)肽化合物的方法非常有限。自然界中可以使用酶催化的c-h鍵的官能團(tuán)化構(gòu)建復(fù)雜的、具有生物活性的天然產(chǎn)物,如vancomycin,celogentin,streptide等(圖1)。

目前,大環(huán)環(huán)肽化合物主要通過以下方法進(jìn)行合成:

1)各種縮合反應(yīng)及取代反應(yīng):如酸胺縮合,sn2反應(yīng)(frost,j.r.,scully,c.c.g.&yudin,a.k..nat.chem.2016,3,1105.),snar反應(yīng)(spokoyny,a.m.etal.j.am.chem.soc.2013,135,5946.)。

2)金屬催化的轉(zhuǎn)化:如疊氮一炔烴環(huán)加成反應(yīng),烯烴關(guān)環(huán)復(fù)分解反應(yīng)(kimy.-w.,grossmannt.n.&verdine,g.l.nat.protoc.2011,6,761.),這些反應(yīng)可以用于訂書肽的合成。

通過上述現(xiàn)有的大環(huán)化方法可以制備一系列環(huán)肽化合物,以及用于穩(wěn)定具有特定氨基酸序列多肽的二級(jí)結(jié)構(gòu),但是現(xiàn)有方法在成環(huán)過程中需要依靠氫鍵等弱相互作用來(lái)實(shí)現(xiàn),不能直接控制產(chǎn)物的三維結(jié)構(gòu)。綜上所述,環(huán)肽作為一類重要的化合物近些年受到學(xué)術(shù)界和藥物化學(xué)領(lǐng)域科學(xué)家的重點(diǎn)關(guān)注,但是現(xiàn)有合成方法的局限性制約了新型大環(huán)環(huán)肽化合物的合成。



技術(shù)實(shí)現(xiàn)要素:

本發(fā)明的目的之一在于提供一種簡(jiǎn)單實(shí)用的方法,可以從簡(jiǎn)單的線性多肽前體出發(fā),通過關(guān)環(huán)反應(yīng),制備環(huán)肽;目的之二在于制備得到的環(huán)肽由苯環(huán)支撐,不依靠分子內(nèi)的氫鍵,結(jié)構(gòu)新穎。

1.一種通過鈀催化的分子內(nèi)c-h鍵的芳基化反應(yīng),高效制備新型環(huán)肽化合物的制備方法,其特征在于該方法的具體步驟(圖2)。在反應(yīng)瓶中依次加入原料、銀鹽、金屬鈀催化劑、添加劑(additive)以及溶劑,指定溫度下攪拌12小時(shí),冷卻至室溫,加入乙酸乙酯稀釋,硅藻土過濾,濃縮,加入二氯甲烷,飽和碳酸氫鈉水溶液洗滌,有機(jī)相用無(wú)水硫酸鈉干燥,柱層析分離得目標(biāo)產(chǎn)物。

2.本發(fā)明所涉及到的金屬催化劑是金屬pd相關(guān)催化劑,可以是pd(oac)2,也可以是其他二價(jià)pd金屬催化劑。

3.本發(fā)明所涉及到的銀鹽可以是碳酸銀,醋酸銀,三氟乙酸銀,也可以是其他一價(jià)銀金屬催化劑。

4.本發(fā)明所涉及到的添加劑(additive)是羧酸相關(guān)添加劑,可以是2-苯基苯甲酸,也可以是如圖3所示的其他羧酸,催化劑的用量一般為0.5equiv。

5.本發(fā)明所用溶劑是叔丁醇,其用量是為每毫摩爾原料對(duì)應(yīng)使用范圍為40ml至200ml。

6.本發(fā)明所涉及到的反應(yīng)溫度可以在80℃至120℃中的任意溫度下進(jìn)行。

7.本發(fā)明所用原料由氨基酸經(jīng)酸胺縮合得到,但不局限于這些組成片段。

本發(fā)明的優(yōu)點(diǎn)是:

1.本發(fā)明所用各種試劑均可商業(yè)所得,原料來(lái)源廣泛,價(jià)格低廉,且各種試劑常溫常壓下能夠穩(wěn)定存在,操作處理方便,無(wú)須特殊處理。

2、本發(fā)明濃度范圍為5-25mm,不需要高度稀釋,適合大量生產(chǎn)。

3.本發(fā)明操作簡(jiǎn)便,不需要隔絕空氣和水,一步反應(yīng)即可得到兩個(gè)產(chǎn)物。對(duì)設(shè)備要求簡(jiǎn)單,后處理也無(wú)特別要求,大大降低了合成該類化合物的生產(chǎn)成本。

4.本發(fā)明所使用的催化劑用量較低,在保持良好催化效果的同時(shí),達(dá)到了簡(jiǎn)化工藝、降低成本、方便后處理工序,溶劑的回收利用便捷,減少環(huán)境污染等要求。
