本发明属于化合物合成技术领域，尤其涉及一种含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成方法。
背景技术
含cf3基团的化合物通常具有比对应c-h化合物更优异的生物、物理和化学性质，因而被广泛应用于医药、农用化学品和材料科学中。仅在医药领域，就有约30％的临床药物含有氟原子。因此，人们投入了大量努力开发将cf3引入到各种活性有机分子中的方法。该领域中，活化烯烃的三氟甲基化双官能团化反应已被证实是一步构筑复杂分子的强有力反应策略，但非活化烯烃的三氟甲基化反应研究则很少。
吲哚母核是大量天然生物碱和临床药物分子的核心结构，而在吲哚化学中，吲哚啉骨架比其它吲哚对应物(如氧化吲哚)难合成。如下从n-芳基丙烯酰胺合成含cf3氧化吲哚反应式：
含cf3的氧化吲哚既可以通过活化烯烃n-芳基丙烯酰胺或丙烯酰基磺酰胺的三氟甲基化/环化序列反应合成，也可以通过母体氧化吲哚的衍生化反应合成，而对应3-(2,2,2-三氟乙基)吲哚啉的合成却仍是一个巨大的挑战，原因可能是非活化烯烃在反应时容易发生聚合或双键转移。合成3-(2,2,2-三氟乙基)吲哚啉的报道非常少，且这些反应步骤繁琐、底物范围窄、成本高、条件苛刻或剧毒。现有的3-(2,2,2-三氟乙基)吲哚啉合成方法如下列反应式：
合成方法a)合成步骤复杂，且仅有1例；合成方法b)试剂昂贵、底物范围窄；合成方法c)试剂昂贵、且使用过量铜；合成方法d)用到有毒昂贵气体、条件苛刻；合成方法e)反应条件苛刻；另外，理论上氧化吲哚的还原反应也可以生成吲哚啉，但是该还原反应有严重的官能团不耐受问题。因此，开发一个通用、实用、且低成本的含cf3吲哚啉的合成方法十分必要。
技术实现要素：
针对现有技术存在的问题，本发明提供了一种含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成方法，基于非活化烯烃双键作为自由基受体的无金属三氟甲基化/环化自由基串联反应，利用该反应可以一步合成含cf3的吲哚啉和1,2,3,4-四氢异喹啉，该合成方法具有条件温和、操作简单、成本低、底物范围广、和呈现exo选择性等显著优点。
一种含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成方法包括：
开发一个非活化烯烃的无金属三氟甲基化/芳基化反应，通过该串联反应可以从烯丙基胺衍生物出发合成含cf3的吲哚啉和四氢异喹啉。

2)tlc显示原料对甲苯胺消耗完毕后，用100ml饱和nahco3溶液淬灭反应，然后用100.0ml的ch2cl2萃取3次，合并的有机相用50ml食盐水洗涤2次，蒸除有机溶剂得到的固体用体积比5:1的石油醚/乙酸乙酯混合液洗涤，得到白色固体对甲基乙酰苯胺；
3)向保持搅拌的1.492g，10.0mmol的甲基乙酰苯胺和600mg，15.0mmol的naoh和30ml的dmf溶液中加入1.311ml，13.0mmol的2-甲基-3-溴丙烯，得到的混合液用磁力搅拌器在室温搅拌反应；
4)tlc显示对甲基乙酰苯胺消耗完毕后，用食盐水淬灭反应并用ch2cl2萃取3次，蒸除有机溶剂得到的残留物用硅胶进行柱层析，得到无色油状物n-(2-甲基烯丙基)-n-对甲苯基乙酰胺；
步骤二、含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成
1)向放有磁力搅拌子的35ml管状耐压管中依次加入312mg，2.0mmol的cf3so2na、405mg，1.5mmol的k2s2o8、和189mg，1.0mmol的n-(2-甲基烯丙基)乙酰苯胺，然后加入3.0ml溶剂dmso反应混合液在50℃搅拌24h后用2.0ml饱和na2s2o3溶液和15.0ml水淬灭，使用10.0ml的ch2cl2萃取3次，然后蒸除有机溶剂，用硅胶进行柱层析，得到浅黄色油状物产物3-(2,2,2-三氟乙基)吲哚啉和含cf3四氢异喹啉。
进一步的，所述合成底物烯丙基胺1，3和5的反应式为：
进一步的，含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成方法的反应机理为：三氟甲基自由基对底物的非活化双键进行加成，生成烷基自由基中间体a，紧接着a的苯环对分子内的自由基进行捕获，从而实现关环，并生成去芳香化的芳基自由基中间体b，硫酸根负离子自由基攫取中间体b苯环饱和碳上的氢，生成产物吲哚啉和硫酸氢根负离子。

一种含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成方法
步骤一、合成底物烯丙基胺1，3和5
合成底物烯丙基胺1，3和5的反应式为：
向一个放有磁力搅拌子的100ml圆底烧瓶中依次加入1.607g，15.0mmol的甲苯胺、50.0ml的ch2cl2和4.170ml，30.0mmol的et3n，最后加入1.273ml，18.0mmol的乙酰氯，反应混合液在室温用磁力搅拌器进行搅拌；
tlc显示原料对甲苯胺消耗完毕后，用100ml饱和nahco3溶液淬灭反应，然后用100.0ml的ch2cl2萃取3次，合并的有机相用50ml食盐水洗涤2次，蒸除有机溶剂得到的固体用体积比5:1的石油醚/乙酸乙酯混合液洗涤，得到白色固体对甲基乙酰苯胺；

tlc显示对甲基乙酰苯胺消耗完毕后，用食盐水淬灭反应并用ch2cl2萃取3次，蒸除有机溶剂得到的残留物用硅胶进行柱层析，得到无色油状物n-(2-甲基烯丙基)-n-对甲苯基乙酰胺；
步骤二、含cf3吲哚啉和1,2,3,4-四氢异喹啉的合成
从步骤一合成的底物n-(2-甲基丙酰基)乙酰苯胺1a1的三氟甲基化/芳基化反应开始本研究，如下反应式和表1：反应条件优化反应式：
表1反应条件a
a反应条件：1a1(1.0mmol)，cf3so2na(2.0mmol)，氧化剂(1.5mmol)，溶剂(3.0ml)，50℃，24h。b分离产率。c乙酰苯胺的分离产率。d底物1a1的回收率。e5.0-6.0mol/l的癸烷溶液。f该反应在室温进行。
在50℃的二甲亚砜(dmso，序号1)溶剂中，1a1与2当量的cf3so2na和1.5当量的k2s2o8顺利发生反应生成了目标分子3-(2,2,2-三氟乙基)吲哚啉2a1，产率高达83％。使用n,n-二甲基甲酰胺(dmf，序号2)作为反应溶剂时，2a1也能以68％的产率生成，另外还有13％产率的乙酰苯胺生成。副产物乙酰苯胺来源于底物1a1氮原子的氧化性脱保护。其它溶剂中的反应不能生成吲哚啉2a1，这些被测试的溶剂包括四氢呋喃(thf，序号3)，meno2，mecn，ch2cl2，甲苯和etoh(序号4-8)。对一系列氧化剂的对比表明，过氧化叔丁醇(tbhp，序号10)在该自由基环合反应中的活性不如k2s2o8，而其它的氧化剂，如oxone(序号9)，过氧化二叔丁基(dtbp，序号11)，碘苯二乙酯(pida，序号12)和间氯过氧化苯甲酸(mcpba，序号13)，则不能有效地引发该反应序列。在室温和其它完全相同的条件下，该串联反应不能发生，只观察到底物1a1的分解(序号14)。
三氟甲基化吲哚啉2可以从各种烯丙基化的苯胺衍生物1合成得到(如下表2)；
苯环对位有甲基、溴原子或苯基的n-(2-甲基丙酰基)乙酰苯胺衍生物都顺利地与cf3so2na发生反应，以64-86％的产率生成5-位取代的吲哚啉2a2-4。丙酰基和辛酰基保护的吲哚啉2b1,2也可以由对应的酰基苯胺合成得到。磺酰基保护基(pgs)也可以被兼容，甲磺酰基、乙磺酰基、苯磺酰基、对甲苯磺酰基、邻甲苯磺酰基、对溴苯磺酰基、或n,n-二甲基氨磺酰保护的富电子、贫电子和电中性烯丙基化苯胺都可以发生该串联反应，并以中等到高的产率生成对应含cf3的吲哚啉2c-h。苯环邻位有取代基的n-烯丙基乙酰苯胺是挑战性的底物，由于位阻效应，对应的7-甲基吲哚啉2i仅以31％的产率生成。有间位取代基的苯胺衍生物参与反应时则存在区域选择性问题，4-位取代的吲哚啉2j-l和它们的区域异构体6-位取代的吲哚啉2j'-l'同时生成。有趣的是，动力学不稳定的2j-l是主产物。现阶段该选择性尚不能被准确解释，但可能与反应中间体的热力学稳定性有关。
表23-(2,2,2-三氟乙基)吲哚啉合成a,b
a反应条件：1(1.0mmol)，cf3so2na(2.0mmol)，k2s2o8(1.5mmol)，dmso(3.0ml)，50℃，24h。b分离产率。
含cf3四氢异喹啉的合成
表3含cf3四氢异喹啉的合成a,b
a反应条件：1(1.0mmol)，cf3so2na(2.0mmol)，k2s2o8(1.5mmol)，dmso(3.0ml)，50℃，24h。b分离产率。
该反应策略可以拓展到n-烯丙基化的苄胺衍生物(表3)。例如，4-(2,2,2-三氟乙基)-1,2,3,4-四氢异喹啉4a-d可以从苯磺酰基或邻苯磺酰基保护的n-烯丙基苄胺合成得到，产率41-65％。
根据baldwin规则，6-endo-trig和6-exo-trig环化也都是容易发生的反应，为了避免潜在的生成六元环的竞争反应，本研究一开始聚焦在n-(2-甲基烯丙基)底物的三氟甲基化/环化反应。在以上所有反应中都实现了高度的exo选择性之后，我们尝试将反应进一步拓展到简单的n-烯丙基苯胺衍生物。令人高兴的是，在最优条件下n-烯丙基-n-(4-溴苯基)甲磺酰胺5顺利发生该环合反应，并以91％的产率专一地生成5-exo-trig产物6的反应式如下：
简单n-烯丙基苯胺的exo选择性三氟甲基化/环合反应
为了验证该反应的自由基属性，我们实施了自由基捕获实验。加入4当量自由基捕获剂如2,2,6,6-四甲基哌啶氧化物(tempo)、2,6-二叔丁基-4-甲基苯酚(bht)、或1,1-二苯乙烯(dpe)后，最优条件下的模型反应几乎被完全抑制。此外，dpe实验中，dpe-cf3加合物7以32％的产率分离得到。根据以上结果和一些前期报道，我们提出了可能的反应机理。首先，cf3so2na与k2s2o8发生反应生成硫酸根阴离子、硫酸根负离子自由基、和三氟甲磺酰基自由基。三氟甲磺酰基自由基随后分解，释放出一分子so2，转化为三氟甲基自由基。三氟甲基自由基对底物1a1的非活化双键进行加成，生成烷基自由基中间体a。紧接着a的苯环对分子内的自由基进行捕获，从而实现关环，并生成去芳香化的芳基自由基中间体b。最后，硫酸根负离子自由基攫取中间体b苯环饱和碳上的氢，生成产物吲哚啉2a1和硫酸氢根负离子。
自由基捕获实验和反应机理如下：
