Description
技术领域
本发明属于有机硒化学领域,具体涉及一种α,β-不饱和硒类化合物的合成方法。
背景技术
自从硒元素问世以来,含硒化合物得到了快速发展,其作为人体必不可少的微量元素,对人体健康起到了至关重要的作用。其中具有抗肿瘤作用的对苯二亚甲基硒腈得到了人们的密切关注,其简单、快速的合成方法也是人们正在探索的方向。近些年来,有机硒化学得到了更好的发展,将硒原子引入到有机物中的方法大部分是通过硒前体来完成,这些硒前体试剂大都有毒,甚至需要通过复杂的路线来制备,浪费大量的人力物力。那么,如何避免剧毒昂贵的硒前体试剂的使用,寻求经济绿色的方法,如何将有机方法学和构建含硒化合物结合在一起,这将是有机硒化合物研究需要努力的方向。
目前,在公开报道文献中合成α,β-不饱和硒类化合物具体有以下:
1.1987年,Hershberger等人[1]报道了α,β-不饱和硒类化合物的合成方法。此方法以锡取代二芳基乙烯,芳基硒汞为原料,在光照下反应得到目标产物。该方法采用了剧毒的锡取代二芳基乙烯以及芳基硒汞,使得此方法具有很大的局限性。
2.1988年,Khanna等人[2]也报道了α,β-不饱和硒类化合物的合成方法。此方法也采用了毒性较大芳基硒汞作为芳硒基的来源。但避免了锡取代二芳基乙烯的使用,采用了低毒性的碘取代二芳基乙烯。
近年来,α,β-不饱和硒类化合物的构建大多使用有毒的硒汞试剂以及硒醚试剂,这类方法存在着大量的缺点,不符合现代绿色发展的理念。

发明内容
本发明的目的是为了克服现有技术存在的缺点和不足,而提供一种α,β-不饱和硒类化合物的合成方法。
本发明所采取的技术方案如下:α,β-不饱和硒类化合物的合成方法,由芳基硼酸类化合物、单质硒、二芳基乙烯类化合物作为反应底物合成的,化学式如下:
反应采用银催化剂或1价铜催化剂或2价铜催化剂。
反应采用2价铜催化剂。
反应采用DMSO、DMA、DMF中的一种或多种。
反应添加配体,所述配体为联吡啶配体、三联吡啶配体、双酮氮配体、膦配体中的一种。
反应为在100-150℃下进行。
反应时间为最少12小时。
反应在氧气条件下进行。
本发明的有益效果如下:本发明由芳基硼酸类化合物、单质硒、二芳基乙烯类化合物成功反应得到α,β-不饱和硒类化合物,避免了有毒的硒汞试剂以及硒醚试剂,符合现代绿色发展的理念,为今后不饱和硒化合物的合成提供了一种绿色、经济的方法。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将对本发明作进一步地详细描述。
以下所揭露的仅为本发明较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明权利要求所作的等同变化,仍属本发明所涵盖的范围。
实施例1:
在25mL反应管中加入磁子,称取苯硼酸(0.8mmol)、Se粉(0.8mmol)、溴化铜(0.04mmol)、三环己基膦氟硼酸盐(0.04mmol)于反应管中,加毕,然后用双排管抽真空,充氧气,来回三次,在氧气的氛围下加入1,1二苯基乙烯 (0.4mmol)、2ml的DMSO溶液,最后密封反应管,移置120℃的加热器中反应12小时。反应完毕,待冷却后,反应混合物用25mL水稀释,再用70mL 乙酸乙酯萃取三次,收集三次的萃取液。有机相用无水硫酸钠干燥,过滤,减压浓缩,再用石油醚进行柱层析纯化。
以下为对该反应的条件优化过程:
1)催化剂对反应的影响:
表1催化剂对反应的影响
反应条件:0.8mmol苯硼酸(5a),0.8mmol硒粉,0.4mmol 1,1-二苯乙烯(6a),
0.04mmol催化剂,2mL二甲基亚砜,120℃,air,24h,a为分离产率。
如表1所示,首先对钯催化剂进行了尝试,当使用2价钯(PdCl2)和0价钯四三苯基膦钯(Pd(PPh)4)(表1,序号1-2)时,没有拿到目标产物。接下来对镍催化剂进行了尝试,当使用2价镍乙酰丙酮镍(Ni(acac)2)、三苯基膦二氯化镍(Ni(PPh)3Cl2)(表1,序号3-4)时,还是没有反应。当使用三联吡啶六氯化钌(RuCl2(COD))这类贵金属催化剂时(表1,序号5),依然没有想要的产物。随后又对银催化剂进行了尝试,当使用了硝酸银(AgNO3)、碳酸银(Ag2CO3) (表1,序号6-7)后,以35%的收率拿到目标产物,随后,使用氯化亚铜(CuCl)、碘化亚铜(CuI)、氧化亚铜(表1,序号8-10)等1价铜时,收率提高,为50%。紧接着我们继续筛选铜催化剂,当使用氯化铜(CuCl2)、溴化铜(CuBr2)(表1,序号11-12)等2价铜时,可以发现较1价铜相比,收率进一步提高,尤其是使用溴化铜时收率可高达70%,使用其他2价铜(表1,序号13-16),收率大多集中在50%-60%。
2)溶剂对反应的影响:
表2溶剂对反应的影响
反应条件:0.4mmol苯硼酸(5a),0.8mmol硒粉,0.4mmol 1,1-二苯乙烯(6a),0.04mmol溴化铜,2 mL溶剂,120℃,air,24h,a为分离产率。
如表2所示,当使用二甲基亚砜(DMSO)、N,N-二甲基甲酰胺(DMF)等 (表2,序号1-3)极性较大的非质子溶剂时,收率较高,分别为70%、63%、 59%,且DMSO溶剂效果最好。值得注意的是,N-甲基吡咯烷酮(NMP)也作为非质子溶剂(表2,序号4),但没有反应。当时用四氢呋喃(THF)(表2,序号5)等极性较小的非质子溶剂时,反应没有发生。当使用异丙醇(IPA)、乙醇(EtOH)、氯仿等(表2,序号6-8)质子性溶剂时,也没有反应。当时用甲苯(toluene)、环乙烷(表2,序号9-10)等非质子非极性溶剂时,只有甲苯是微量反应。由数据可知,此反应对溶剂的要求比较敏感,只有极性较大的非质子溶剂才能反应。
3)配体对反应的影响:
表3配体对反应的影响
反应条件:0.8mmol苯硼酸(5a),0.8mmol硒粉,0.4mmol 1,1-二苯乙烯(6a),0.04mmol溴化铜,2 mL二甲基亚砜,0.04mmol配体,120℃,air,24h,a为分离产率。
如表3所示,首先筛选了氮配体,当使用了带有胺基的配体(表3,序号 1-5)之后,阻止了反应的发生。继续使用菲啰啉配体时(表3,序号6-7),只有微量的收率。当使用了联吡啶配体(表3,序号8-11)后,反应效果较之前的配体相比较有了明显的上升,收率依次为54%、49%、56%、55%。最后使用了三联吡啶配体(表3,序号12)后,收率进一步提高,达到了63%。接下来选用了双酮氮配体(表3,序号13-14),收率达到了75%。在筛选了氮配体之后,尝试了膦配体,选用便宜易得的三苯基或三环己基膦配体(表3,序号15-19),其收率都在70%左右,当使用了带有酸性的三环己基膦氟硼酸盐配体时(表3,序号20),收率提高到了82%。
4)温度、反应时间、氛围对反应的影响:
表4时间、温度、氛围对反应的影响
反应条件:0.8mmol苯硼酸(5a),0.8mmol硒粉,0.4mmol 1,1-二苯乙烯(6a),0.04mmol溴化铜,2mL 二甲基亚砜,0.04mmol L20配体,temp,time,atmo,a为分离产率。
如表4所示,在室温下(表4,序号1)反应,结果没有拿到目标产物,继续升温到80℃(表4,序号2)时,还是没有反应,升温到120℃(表4,序号 3)时,以82%的收率拿到产物,继续升温至150℃(表4,序号4),收率下降了10%左右,因此最佳的温度为120℃。接下来对反应氛围进行了筛选,结果显示在氮气氛围下(表4,序号6)反应收率有所下降,而在氧气氛围下(表4,序号5)收率进一步提高,可能是氧气起到了氧化的作用。最后又对反应时间进行了筛选,当反应时间降到12小时时(表4,序号7),收率持平,但继续降低反应时间(表4,序号8-9),收率大幅度下降。
综上所述,以苯硼酸、单质Se和1,1-二苯乙烯为起始原料反应合成α,β- 不饱和硒类化合物的最优条件为:在氧气的氛围下,0.8mmol苯硼酸,0.8mmol 硒粉,0.4mmol 1,1-二苯乙烯,0.04mmol溴化铜,0.04mmol三环己基膦氟硼酸盐,2mL二甲基亚砜,120℃,12h。
实施例2芳基硼酸底物的拓展:
如表5所示,在最优条件下,进行了芳基硼酸(表5,7a-7w)的底物拓展。首先考虑的是位阻效应,从结果来看,对位的收率普遍要大于邻位和间位(表5, 7b-7g),相差了10%-30%不等。此外,我们还在邻位和间位分别选取了给电子基团和吸电子基团(表5,7b-7f),结果显示,具有吸电子效应的卤素基团的收率要高于给电子的甲基基团,具体为间位72%>60%,邻位55%>49%。具有给电子效应的烷基和苯基(表5,7i-7j),收率为72%,76%。此外,萘环和噻吩环(表5,7m,7n)也取得了不错的收率,分别为79%、55%。值得注意的是,三甲基硅取代基的苯硼酸(表5,7h)也有68%的收率,这就为后续的衍生反应提供了较大的平台。带有大位阻的苯硼酸(表5,7l)虽然只有40%的收率,这也足够证明,此反应体系能容忍大位阻的试剂。此外,具有吸电子的卤素基团 (表5,7o-7s)有80%左右的收率,氟取代的苯硼酸收率高达了82%,此外,具有吸电子效应的酯基(表5,7k)也有66%的收率,可见吸电子基团更能够推促反应的进行。接下来选择了噻唑和吡啶杂环的硼酸(表5,7t,7u)进行了尝试,没有拿到目标产物。最后考察了烷基硼酸(表5,7v,7w),同样也没有拿到目标产物。
表5芳基硼酸底物拓展
反应条件:0.8mmol芳基硼酸(5a),0.8mmol硒粉,0.4mmol 1,1-二苯乙烯(6a),0.04mmol溴化铜,2 mL二甲基亚砜,0.04mmol配体,120℃,氧气,12h,a为分离产率。
实施例3二芳基乙烯底物的拓展:
1.二芳基乙烯的制备:在装有磁子、恒压滴液漏斗的150mL茄形瓶中,称取相应的苯乙酮(10.0mmol,1.0equiv)于茄形瓶中,密封之后,然后再抽真空,充氮气,来回三次,在氮气的保护下加入无水乙醚30ml,再量取苯基格式试剂(15.0mmol,1.5equiv)于恒压滴液漏斗中,让其在冰水浴中慢慢滴下,反应3小时后,加入3ml的亚磷酸二乙酯,加毕,继续反应24小时后,移除冰水浴,加入蒸馏水于茄形瓶中,搅拌片刻后,用无水乙醚进行萃取,萃取液在旋转蒸发仪上减压浓缩。然后再用柱色谱分离,分离的极性根据产物的不同而调整。
2.不同二芳基乙烯作为底物合成α,β-不饱和硒类化合物:
如表6所示,二芳基乙烯化合物为邻位带有取代基团的非对称二芳基乙烯 (表6,8a-8b),收率分别为55%、49%。二芳基乙烯化合物为间位带有给电子的甲基时(表6,8c),收率为60%,吸电子的卤素时(表6,8d),收率为72%,间位的收率较邻位相比有所上升,当对位是卤素基团时(表6,8f-8g),收率集中在70%左右,但是,取代基为甲基,甲硫基,萘基时(表6,8h-8j),收率分别为72%,76%,66%,接下来,一边是卤素,一边是烷基的二芳基乙烯我们也进行了考察(表6,8k,8l),收率为80%、68%,两边都是烷基取代基二芳基乙烯的收率为44%(表6,8e),接下来,具有对称结构的对氯二芳基乙烯达到 73%的收率(表6,8m),非对称的双卤结构收率为69%(表6,8n),二芳基乙烯化合物为3,4,5-三甲氧基二芳基乙烯(表3-6,8o),很可惜没有拿到目标产物,可能是由于电子效应导致的。
表6二芳基乙烯底物拓展
反应条件:0.8mmol苯硼酸(5a),0.8mmol硒粉,0.4mmol二芳基乙烯(6a),0.04mmol溴化铜,2mL 二甲基亚砜,0.04mmol配体,120℃,氧气,12h,a为分离产率。
实施例4反应机理的研究:
为了弄清反应机理,如表7所示,使用苯硼酸和单质Se在标准条件下进行反应(表7,eq 1),结果以87%的收率得到了二苯基二硒醚,然后在不存在CuBr2 的情况下(表7,eq2)进行反应,结果没有得到二硒醚,紧接着我们在标准条件加入了3equiv TEMPO(表7,eq3),没有得到二硒醚,由此可见,金属铜催化剂在苯硼酸和单质Se的反应中起到了重要作用。接下来,我们用二苯基二硒醚和1,1-二苯乙烯在标准条件下和不加CuBr2、配体的条件下反应(表7,eq 4-6),最终分别以47%、39%、35%的收率得到了目标产物,结果显示,铜催 化剂和配体不是反应的必须条件,但是CuBr2起到了促进作用。然后我们在eq5的基础上加入了3equiv TEMPO(表7,eq 7),结果没有目标产物的生成。最后我们进行了分步实验(表7,eq 8),没有目标产物的生成,由此可知,反应并不是通过二硒醚中间体来完成的。
表7反应机理的研究
通过以上实验,可以推测反应机理如下:
首先,Cu(II)促进苯硼酸产生苯基自由基(过程中Cu(II)被还原成Cu(I)),然后被Se捕获,形成苯硒基自由基,然后进攻1,1-二苯乙烯形成苯硒基-二苯基自由基,紧接着在氧气的作用下、去质子化得到目标产物,最后Cu(I)被氧气氧化成Cu(II),反应由此循环,剩下的双游离苯硒自由基耦合产生二苯基二硒醚,这就解释了反应过程中为什么会有二苯基二硒醚的生成。
