    4-苯酚重氮盐与各种苯乙烯进行Pd催化的Heck反应,生成4'-羟基苯乙烯。与类似的4-甲氧基苯重氮盐相比,几乎在所有情况下均观察到更高的收率和更少的副产物。相反,用2-和3-苯酚重氮盐使反应完全失败。对于这些取代方式,甲氧基取代的衍生物是优越的。

    公开号:US20130053598A1
    公开(公告)日:2013-02-28
    The invention relates to a method for producing a cross-coupling product of a benzenoid dizonium salt according to the general formula (I), wherein the groups R 1 , R 2 , R 3 , R 4 , and R 5 represent hydrogen, halogen, an alkyl, alkenyl, aryl, alkoxy, aryloxy, nitro, cyano, hydroxy, acetyl, and/or diazo groups independently of each, and X represents BF 4 , Cl, F, SO 3 CH 3 , CO 2 CH 3 , PF 6 , ClO 2 CH 3 , or CIO 4 , comprising the following steps: (a) providing a benzenoid amide, which with the exception of the diazo function has the same substituents R 1 , R 2 , R 3 , R 4 , and R 5 as the benzenoid diazonium salt of the general formula (I), and hydrolytically cleaving the amide to form an amine or providing a corresponding amine, (b) diazotizing the amine thus obtained or provided with a nitrite, and (c) subsequently reacting the benzenoid diazonium salt with a coupling partner in the presence of a catalyst to form a cross-coupling product, wherein the coupling parter is represented by the general formula (II), R 6 , R 7 , and R 8 are the same or different and represent hydrogen, carboxyalkyl groups, carboxyaryl groups, alkyl groups, aryl groups, alkoxy groups, aryloxy groups, wherein the groups can each contain Si, N, S, O, and or halogen atoms, or R 6 and R 7 with the double bound form an aromatic ring, which can be provided with R 8 and one to four further substituents, independently of each other, selected from the group comprising a straight-chain or branched (C 1 -C 6 ) alkyl group, a (C 3 -C 7 ) cycloalkyl group, a straight-chain or branched (C 1 -C 6 ) alkenyl group, a straight-chain or branched (C 1 -C 6 ) alkyoxy group, halogen, the hydroxy group, an amino, di(C 1 -C 6 ) alkylamino, nitro, acetyl, cyan, benzyl, 4-methoxybenzyl, 4-nitrobenzyl, phenyl, and 4-methoxyphenyl group and represents Y=H, —B(OR) 2 , —SnR 3 , —ZnR, —SiR 3 , or Mg (halogen), and wherein at least the steps (b) and (c) are performed without intermediate isolation of an intermediate product. According to said method, cross-couplings can be performed more simply and with improved yield without the hydroxyl group in aromatic reactants containing hydroxyl groups having to be provided with a protective group.
    该发明涉及一种根据通式(I)制备苯并重氮盐的交叉偶联产物的方法,其中基团R1、R2、R3、R4和R5代表氢、卤素、烷基、烯基、芳基、烷氧基、芳氧基、硝基、基、羟基、乙酰基和/或重氮基,X代表BF4、Cl、F、SO3CH3、CO2CH3、PF6、ClO2CH3或CIO4,包括以下步骤:(a)提供苯并酰胺,除了重氮功能外,具有通式(I)中苯并重氮盐相同的取代基R1、R2、R3、R4和R5,并解裂解酰胺形成胺或提供相应的胺,(b)用亚硝酸盐重氮得到或提供的胺,(c)随后在催化剂存在下将苯并重氮盐与偶联配体反应形成交叉偶联产物,其中偶联配体由通式(II)表示,R6、R7和R8相同或不同,代表氢、羧基烷基、羧基芳基、烷基、芳基、烷氧基、芳氧基,其中基团可以包含Si、N、S、O和/或卤素原子,或R6和R7与双键形成芳香环,可提供R8和一个到四个进一步取代基,独立于彼此,选自包括直链或支链(C1-C6)烷基、(C3-C7)环烷基、直链或支链(C1-C6)烯基、直链或支链(C1-C6)烷氧基、卤素、羟基、基、二(C1-C6)烷基基、硝基、乙酰基、基、苄基、4-甲氧基苄基、4-硝基苄基、苯基和4-甲氧基苯基,表示Y=H、—B(OR)2、—SnR3、—ZnR、—SiR3或Mg(卤素),至少步骤(b)和(c)在不中间分离中间产物的情况下执行。根据该方法,可以更简单地进行交叉偶联,并且在含有羟基的芳香反应物中无需提供保护基即可获得改进的产率。

    Significantly better yields were achieved in Mizoroki–Heck reactions using 4-phenoldiazonium salts instead of their O-alkylated analogues under otherwise identical conditions. We found that a one-flask deacetylation–diazotation–precipitation sequence starting from paracetamol or acetanilides derived thereof provides a convenient access to the required diazonium tetrafluoroborates. The utility of these
    在其他条件相同的条件下,使用4-苯酚重氮盐代替O-烷基化类似物,在Mizoroki-Heck反应中获得了明显更高的收率。我们发现,从扑热息痛扑热息痛衍生的对乙酰苯胺开始的一烧瓶式脱乙酰化-重氮化反应-沉淀序列为获得所需的重氮四硼酸盐提供了便利。这些芳基化剂在催化的CC键形成反应中的实用性已被证明可用于一瓶合成药物阿立哌唑的杂环核心。值得注意的是,由乙苯胺形成的重氮盐可与两个Pd催化的步骤以一个烧瓶的顺序合并,而无需任何溶剂交换或中间体分离。

    Arene diazonium salts undergo Matsuda–Heck reactions with vinylsulfonates and -sulfonamides to give styrylsulfonic acid derivatives in high to excellent yields and with high to excellent selectivities. By quantifying the evolution of nitrogen over time in a gas-meter apparatus, the reactivities of ethylvinylsulfonate and the benchmark olefin methyl acrylate were compared for an electron-rich and an

This correlation revealed that in the case of the six-membered lactone an energetically favorable conformer adopts a nearly synperiplanar Pd/endo-β-H arrangement, whereas for the analogous Pd σ-complex of the five-membered lactone the smallest Pd/endo-β-H dihedral angle is observed for a conformer with a comparatively high potential energy
