,涉及含氮環(huán)番化合物的制備方法。
背景技術(shù)
:在醫(yī)藥工業(yè)中,新藥發(fā)現(xiàn)是決定醫(yī)藥產(chǎn)業(yè)興衰的主要因素,而天然產(chǎn)物具有良好的生物活性,是新藥發(fā)現(xiàn)的重要組成部分,1981年至2011年的30年間,全球已獲批的小分子新藥共1355種,其中63%來源于天然產(chǎn)物及其衍生物。環(huán)番是一類含苯等芳香環(huán),以亞甲基和雜原子作為骨架橋的環(huán)狀分子。由Cram和Steinberg于1951年首次合成出來,并命名為環(huán)番(DONALDJ.CRAMANDH.STEINBE.J.Am.Chem.Soc.1951,73,5691-5704)。通常,根據(jù)環(huán)番空腔的大小分為小環(huán)番和大環(huán)番。小環(huán)番,張力較大,導(dǎo)致環(huán)番中的芳環(huán)變形,其物理、化學(xué)性質(zhì)都不同于一般芳烴,表現(xiàn)出許多有趣的特性,如跨環(huán)電子效應(yīng)和環(huán)加成等。大環(huán)番其中的芳環(huán)的平面性,電子性以及反應(yīng)活性與一般的芳烴區(qū)別不大。由于其獨(dú)特的化學(xué)結(jié)構(gòu)和新奇的性質(zhì),環(huán)番類大環(huán)化合物已經(jīng)廣泛應(yīng)用于分子識(shí)別、超分子聚合物等諸多研究領(lǐng)域。許多天然產(chǎn)物含有大環(huán)番結(jié)構(gòu),比如:以及(CyclindrocyclophaneA)。這些天然產(chǎn)物都表現(xiàn)出了良好的生物活性,比如:HauamineA具有抗結(jié)腸癌細(xì)胞活性(IC50=0.1μg/mL),抗PC3前列腺癌細(xì)胞活性(IC50=29±2μg/mL),CyclindrocyclophaneA對(duì)KB和LoVo腫瘤細(xì)胞系具有很強(qiáng)的活性(IC50=2-10μg/mL)。天然產(chǎn)物分離難度高、分離效率低、來源稀少等因素大大限制了對(duì)其的生物活性研究和產(chǎn)業(yè)化開發(fā)。然而,有機(jī)化學(xué)全合成的出現(xiàn)使得這個(gè)問題迎刃而解。通過合理實(shí)驗(yàn)設(shè)計(jì),人類能夠制備天然產(chǎn)物。因此,高效選擇性的構(gòu)建環(huán)番結(jié)構(gòu)化合物對(duì)醫(yī)藥工業(yè)發(fā)展有著十分重要的意義,發(fā)展高效的化學(xué)合成方法對(duì)獲得天然產(chǎn)物是十分必要的。目前,國內(nèi)外文獻(xiàn)報(bào)道的對(duì)于環(huán)番結(jié)構(gòu)化合物的合成方法僅有有限的幾種方法。在對(duì)天然產(chǎn)物HaouamineA的全合成研究中,PeterWipf(PeterWipf,MarkusFuregati.Org.Lett,2006,8(9),1901–1904)發(fā)展了芳構(gòu)化合成策略得到分子片段,在170℃下反應(yīng),產(chǎn)率90%,反應(yīng)過程如下:PhilS.Baran(PhilS.Baran,NoahZ.BurnsJ.Am.Chem.Soc.,2006,128(12),3908–3909)發(fā)展了一條運(yùn)用分子內(nèi)Diels-Alder反應(yīng)策略完成HaouamineA的全合成,使用分子內(nèi)吡喃酮-炔Diels-Alder反應(yīng)體系作為關(guān)鍵反應(yīng),在微波250℃下反應(yīng)10小時(shí),產(chǎn)率21%,反應(yīng)過程如下:在對(duì)天然產(chǎn)物CylindrocyclophanesA的全合成研究中,K.C.Nicolaou(K.C.Nicolaou,Ya-PingSun,HenryKorman.Angew.Chem.Int.Ed.2010,49,5875–5878)發(fā)展了使用Ramberg-反應(yīng)作為關(guān)鍵反應(yīng)得到環(huán)番體系,包括三步反應(yīng),操作繁瑣,且使用昂貴金屬反應(yīng)試劑,原子經(jīng)濟(jì)性不高,反應(yīng)過程如下:AmosB.Smith(AmosB.Smith,ChristopherM.AdamsJ.Am.Chem.Soc.,2001,123(25),5925–5937)發(fā)展了運(yùn)用分子內(nèi)烯烴復(fù)分解反應(yīng)作為關(guān)鍵反映的合成策略,使用Grubbs(I)反應(yīng)試劑反應(yīng)22小時(shí),可以得到環(huán)番體系,反應(yīng)時(shí)間長,且需要高濃度稀釋,反應(yīng)過程如下:然而,這些反應(yīng)往往有收率低、反應(yīng)條件苛刻(溫度過高、反應(yīng)時(shí)間長)、底物不適應(yīng)、難以產(chǎn)業(yè)化等限制和弊端。因此,發(fā)展新穎、高效、底物適應(yīng)性高并適于產(chǎn)業(yè)化的環(huán)番化合物的合成方法是十分必要的。光延(Mitsunobu)反應(yīng)可用于分子內(nèi)含氮雜環(huán)結(jié)構(gòu)的制備。據(jù)TohruFukuyama等人(Angew.Chem.Int.Ed.2012,51,9160–9163;Org.Lett.2007,9,4737)報(bào)道,分子內(nèi)光延反應(yīng)可以用于十元、十一元含氮大環(huán)化合物的合成,反應(yīng)式如下:但是,通過該方法并不能制備含氮環(huán)番化合物。首先,含氮環(huán)番化合物具有獨(dú)特的空間構(gòu)象,分子環(huán)張力不同,研究人員嘗試了常規(guī)關(guān)環(huán)反應(yīng),均不能制備含氮環(huán)番化合物。其次,涉及到的反應(yīng)底物若為芳香胺類,與脂肪胺相比,其活性更弱,增大了制備該系列化合物的難度。技術(shù)實(shí)現(xiàn)要素:本發(fā)明目的在于提供一種制備含氮環(huán)番化合物的方法,運(yùn)用分子內(nèi)光延反應(yīng)來合成含氮環(huán)番化合物,在溫和的加熱條件下,就可一步制備結(jié)構(gòu)復(fù)雜的含氮環(huán)番體系,副產(chǎn)物極易溶于水,大大簡化了后處理過程。反應(yīng)過程中并未檢測(cè)到其他副反應(yīng)的發(fā)生,收率60%-80%,該反應(yīng)的高效及高選擇性使大量制備結(jié)構(gòu)復(fù)雜的含氮環(huán)番體系成為可能。反應(yīng)所用試劑價(jià)格低廉、后處理簡單,具有很高的原子經(jīng)濟(jì)性。本發(fā)明為制備該系列化合物提供了一種簡潔、高效、價(jià)格低廉、選擇性高并適于產(chǎn)業(yè)化的反應(yīng)體系。本發(fā)明中,解決技術(shù)問題所采用的技術(shù)手段是,選擇有機(jī)磷化合物和偶氮試劑組合物作 為反應(yīng)試劑組合物,反應(yīng)溫度是關(guān)鍵參數(shù)。通過底物擴(kuò)展研究,提高了該反應(yīng)的底物適應(yīng)性,在復(fù)雜結(jié)構(gòu)天然產(chǎn)物全合成中,可以作為關(guān)鍵反應(yīng)制備含氮大環(huán)結(jié)構(gòu)。最重要的是,發(fā)明人員驚奇的發(fā)現(xiàn)溫度是本發(fā)明中的一個(gè)關(guān)鍵因素,而在現(xiàn)有技術(shù)所描述制備方法中,室溫條件下并不能制備該系列化合物,回流溫度會(huì)導(dǎo)致產(chǎn)率降低。發(fā)明人員發(fā)現(xiàn)了運(yùn)用本發(fā)明的技術(shù)手段可以成功的應(yīng)用于一系列含氮環(huán)番化合物的制備,反應(yīng)通式可由如下路徑(1)、(2)、(3)表示:路徑(1)中反應(yīng)底物R1、R6為氫原子,R2為甲基、乙基、異丙基,R3、R4、R5為甲氧基,R8、R9為甲基、乙基,R10、R11、R12為氫、甲基、乙基或異丙基,X為氧,n=1-9。路徑(2)中反應(yīng)底物R14、R15為甲氧基,R13為甲基、乙基、異丙基,R8為甲基、乙基,R10、R11、R12為氫、甲基、乙基、異丙基,X為氧,n=2-13。路徑(3)中反應(yīng)底物R14、R15為甲氧基,R13為甲基、乙基、異丙基,R8為甲基、乙基,R10、R11、R12為氫、甲基、乙基、異丙基,R16為氫,X為氧,n=1-13。所述的制備方法包括以下操作:將底物置于單頸燒瓶中,氮?dú)獗Wo(hù),加入適量任選的合適有機(jī)溶劑溶解,先后將有機(jī)磷化合物和偶氮試劑加入到燒瓶中。燒瓶置于油浴環(huán)境下反應(yīng),用薄層色譜TLC檢測(cè)至反應(yīng)液中無原料時(shí)為反應(yīng)結(jié)束。將反應(yīng)液有機(jī)溶劑旋干,并用任何合適的有機(jī)溶劑溶解所得固體物質(zhì),加入少量水進(jìn)行萃取,合并有機(jī)相,用硫酸鈉干燥,過濾,旋干溶劑,經(jīng)硅膠柱層析,純化得到固體產(chǎn)物。本發(fā)明中,反應(yīng)溫度范圍選擇60-100℃,優(yōu)選70-90℃,最優(yōu)選80℃。本發(fā)明中,所述反應(yīng)試劑組合物中有機(jī)磷化合物優(yōu)選三正丁基膦,偶氮試劑優(yōu)選N,N,N',N'-四甲基偶氮二甲酰胺,二者的摩爾比為1:1。本發(fā)明中,反應(yīng)底物與反應(yīng)試劑組合物的用量摩爾比范圍選擇1:1-1:8,優(yōu)選1:2-1:6,最優(yōu)選1:4。本發(fā)明中,反應(yīng)體系有機(jī)溶劑優(yōu)選苯、甲苯,最優(yōu)選甲苯。本發(fā)明還提供了根據(jù)本發(fā)明所涉及的制備方法所制備的一系列化合物,以及這些化合物在制備適用于抗腫瘤藥物和/或抗菌藥物中的用途。這些化合物還可與藥學(xué)上可接受的輔料組合,制成制劑組合物;還可與其他抗腫瘤或抗菌活性成分組合,制成復(fù)方制劑組合物。具體實(shí)施方式本發(fā)明的任一實(shí)施方案中的監(jiān)控方法是:薄層層析法。結(jié)構(gòu)確證技術(shù)手段均為本領(lǐng)域技術(shù)人員知曉的通用技術(shù)手段,核磁共振技術(shù),高分辨質(zhì)譜。實(shí)施例1:化合物1-1g的制備步驟1:將反應(yīng)物1-1a(700mg,1.64mmol)置于干燥的50mL裝有轉(zhuǎn)子的雙頸瓶中,雙頸瓶置于500mL杜瓦瓶中,N2保護(hù),脫氣后,將50mL乙醚加入杜瓦瓶中,并加入液氮至乙醚凝為固體,用注射器加入10mL無水四氫呋喃。然后用注射器將正丁基鋰(2.7mL,6.6mmol)逐滴加入至反應(yīng)液中,加完后攪拌15分鐘。將反應(yīng)物1-1b(705mg,2.5mmol)溶解于5mL無水四氫呋喃中,用注射器逐滴加入反應(yīng)液中,反應(yīng)液在-100℃下反應(yīng)20分鐘后升至室溫。逐滴加入飽和氯化銨溶液淬滅反應(yīng),15mL乙酸乙酯萃取三次,合并有機(jī)相,用飽和氯化鈉溶液洗滌后,用無水硫酸鈉干燥后過濾,旋蒸除去溶劑得到油狀物,用柱層析分離得到黃色油狀物697mg,產(chǎn)率67%。黃色油狀物(Rf=0.3EtOAc/PE=1:7)1HNMR(400MHz,Chloroform-d)δ7.88(s,1H),7.70(s,1H),7.11(s,1H),5.60(d,J=13.2Hz,1H),4.69(d,J=12.0Hz,1H),4.11–3.72(m,9H),3.56(t,J=6.6Hz,2H),2.45(s,3H),2.03–1.64(m,2H),1.64–1.17(m,23H),0.87(s,9H),0.02(s,6H).13CNMR(101MHz,Chloroform-d)δ154.76,152.84,136.09,131.97,126.73,122.37,119.52,99.39,80.75,69.48,63.31,61.82,61.27,55.79,38.44,32.87,29.55,28.37,27.03,25.96,25.82,29.69,29.43,29.27,18.34,17.51,-5.28.步驟2:將反應(yīng)物1-1c(240mg,0.46mmol)置于干燥的裝有轉(zhuǎn)子的50mL單頸瓶中,N2保護(hù),加入16mL干燥的二氯甲烷溶解,戴斯-馬丁氧化劑(235mg,0.56mmol)緩慢加入到反應(yīng)液中,攪拌5分鐘后,加入少量NaHCO3溶液淬滅反應(yīng),并過濾,反應(yīng)液用飽和食鹽水洗滌后,用無水硫酸鈉干燥并過濾,旋蒸除去溶劑,用柱層析分離得到產(chǎn)物1d220mg,產(chǎn)率96%。黃色油狀物(Rf=0.35EtOAc/PE=1:7)1HNMR(400MHz,Chloroform-d)δ7.74(s,1H),7.70(s,1H),7.11(s,1H),3.97–3.64(m,9H),3.58(td,J=6.6,1.9Hz,2H),2.85(dddd,J=17.4,9.8,5.6,1.9Hz,1H),2.72–2.55(m,1H),2.44(d,J=1.9Hz,3H),1.80(h,J=7.4Hz,1H),1.74–1.62(m,1H),1.62–1.42(m,9H),1.42–1.11(m,12H),0.88(d,J=2.0Hz,9H),0.05(dd,J=10.8,1.9Hz,6H).13CNMR(101MHz,Chloroform-d)δ206.62,152.78,151.59,151.17,135.50,132.21,131.14,127.85,125.36,122.96,118.05,98.74,80.75,63.29,62.67,61.35,56.12,44.94,32.86,29.51,29.36,29.23,28.36,25.96,25.78,23.43,18.34,16.77,-5.28.步驟3:將反應(yīng)物1-1d(150mg,0.29mmol)置于干燥的裝有轉(zhuǎn)子的50mL單頸瓶中,N2保護(hù),加入30mL干燥的二氯甲烷溶解,用注射器將三氟乙酸10mL逐滴加入反應(yīng)液中,在常溫下攪拌12小時(shí)后,用飽和NaHCO3溶液調(diào)節(jié)pH至中性,反應(yīng)混合液用二氯甲烷萃取三次,合并有機(jī)相,用無水硫酸鈉干燥并過濾,旋蒸除去溶劑,用柱層析分離得到產(chǎn)物112mg,產(chǎn)率92%。黑色油狀物(Rf=0.25EtOAc/PE=1:2)1HNMR(400MHz,Chloroform-d)δ7.66(s,1H),6.40(s,1H),5.22(brs,3H),4.33(t,J=6.7Hz,2H),3.93–3.59(m,9H),2.85(ddd,J=18.6,9.5,5.7Hz,1H),2.68(ddd,J=18.0,9.2,5.7Hz,1H),2.43(s,3H),1.89–1.55(m,4H),1.50–1.28(m,10H).13CNMR(101MHz,Chloroform-d)δ207.25,151.56,151.05,135.39,132.41,131.04,126.40,122.59,117.45,98.83,68.26,62.62,60.73,56.02,44.91,29.34,29.25,29.17,28.99,28.07,25.45,23.38,16.74.步驟4:將反應(yīng)物1-1e(80mg,0.2mmol)置于干燥的裝有轉(zhuǎn)子的50mL單頸瓶中,N2保護(hù),加入20mL二氯甲烷溶解,用注射器將干燥吡啶(32μL,0.4mmol)逐滴加入反應(yīng)液中,4-硝基苯磺酰氯(89mg,0.4mmol)加入反應(yīng)液中,反應(yīng)在常溫下攪拌12小時(shí)后,加入少量飽和NaHCO3,用二氯甲烷萃取三次,合并有機(jī)相,用無水硫酸鈉干燥,過濾,旋蒸除去溶劑,用柱層析分離得到產(chǎn)物90mg,產(chǎn)率74%。黃色油狀透明液體(Rf=0.4EtOAc/PE=1:2)1HNMR(400MHz,Chloroform-d)δ8.24(d,J=8.4Hz,2H),7.96(d,J=8.4Hz,2H),7.59(s,1H),7.25(s,1H),7.13(s,1H),4.34(t,J=6.7Hz,2H),3.87(s,3H),3.70(s,3H),3.50(s,3H),2.85(ddd,J=18.2,9.3,5.7Hz,1H),2.69(ddd,J=18.0,9.1,5.8Hz,1H),2.40(s,3H),1.73(dddd,J=29.8,20.1,14.2,6.2Hz,4H),1.36(d,J=16.7Hz,10H).13CNMR(101MHz,Chloroform-d)δ206.24,152.87,151.69,150.24,144.59,138.56,133.20,131.50,128.30,125.31,124.59,124.35,123.54,120.14,99.05,68.25,62.60,62.20,56.27,44.88,29.39,29.27,29.19,29.00,28.07,25.46,23.36,16.73.步驟5:將反應(yīng)底物1-1f(50mg,0.08mmol)置于干燥的裝有轉(zhuǎn)子的25mL單頸瓶中,N2保護(hù),加入15mL干燥的甲苯溶解,用注射器將三丁基膦(41.4μL,0.16mmol)逐滴加入反應(yīng)液中,N,N,N',N'-四甲基偶氮二甲酰胺(29mg,0.16mmol)加入反應(yīng)液中,反應(yīng)在60℃油浴中攪拌6小時(shí)后,旋蒸除去溶劑,用二氯甲烷溶解,加入少量水,萃取三次,合并有機(jī)相,用無水硫酸鈉干燥并過濾,用柱層析分離得到產(chǎn)物33.1mg,產(chǎn)率68%。黃色固體(Rf=0.6EtOAc/PE=1:2)1HNMR(400MHz,Chloroform-d)δ8.38(d,J=8.5Hz,2H),8.10(d,J=8.5Hz,2H),7.88–7.75(m,1H),6.43(s,1H),3.87–3.60(m,11H),2.62(td,J=6.3,2.3Hz,2H),2.47(s,3H),1.75–1.51(m,6H),1.53–1.26(m,1H),0.99–0.36(
