    吡唑在β位的CH键芳基化:一般条件和对高区域选择性的计算阐明
    摘要:
    大多数五元环杂环的直接芳基化通常很容易获得,并且使用经典的钯催化作用在α位置受到强烈支持。相反,在同时存在的β位置,此类杂环的区域选择性功能化目前仍然非常具有挑战性。在本文中,我们报道了吡唑在β-位置的区域选择性直接芳基化的一般条件,而C-Hα-位置是自由的。通过使用芳基溴化物作为芳基来源并明智地选择溶剂,各种N-取代的吡唑的芳基化反应只需通过β-C-H键官能化即可进行。无配体的钯催化剂和不含氧化剂或其他添加剂的简单碱可提高β-区域选择性,并能耐受溴芳烃上的各种取代基。DFT计算表明,质子溶剂(例如2-乙氧基乙烷-1-醇)显着提高了吡唑在β位的质子酸度,因此有利于这种直接的β-CH键直接芳基化。这种选择性的吡唑β-CH键芳基化成功地通过进一步的Pd催化的α-CH键分子间和分子内CH键的芳基化而成功地直接构建了π-延伸的聚(杂)芳族结构。原子经济过程。

    Aryl/heteroaryl pentafluorobenzenesulfonates (ArOPFBs): new electrophilic coupling partners for room temperature Suzuki–Miyaura cross-coupling reactions
    摘要:
    The first cross-coupling reaction between aryl/heteroaryl pentafluorobenzenesulfonates and aryl/heteroaryl boronic acids under mild conditions is described. The successful synthesis of highly ortho substituted biaryls and high chemoselectivity of these bench stable intermediates over tosylates, triflates, mesylates, and chlorides increases its scope as a valuable cross-coupling partner. The generality of this protocol was further extended to other boron containing nucleophiles (boronates, trifluoroborates) and alkyl boronic acids. (C) 2015 Elsevier Ltd. All rights reserved.

  • Synthesis of Redox-Active Phenanthrene-Fused Heteroarenes by Palladium-Catalyzed C–H Annulation
    作者:Jin Hyeok Jang、Seongmo Ahn、Soo Eun Park、Soeun Kim、Hye Ryung Byon、Jung Min Joo
    DOI:10.1021/acs.orglett.9b04545
    日期:2020.2.21
    Pd-catalyzed C-H annulation reactions of halo- and aryl-heteroarenes were developed using readily available o-bromobiaryls and o-dibromoaryls, respectively. A variety of five-membered heteroarenes rapidly provided the corresponding phenanthrene-fused heteroarenes, which led to the identification of phenanthro-pyrazole and thiazole as new, stable -2 V redox couples. The flexible syntheses and tunability
    分别使用容易获得的邻溴二芳基和邻二溴芳基开发了Pd催化的卤代芳基和芳基杂芳烃的CH环合反应。各种五元杂芳烃迅速提供了相应的菲稠杂芳烃,从而将菲咯并吡唑和噻唑鉴定为新的,稳定的-2 V氧化还原对。这些唑类稠合的菲在很宽的范围内具有灵活的合成能力和氧化还原电位的可调性,有望促进它们作为氧化还原活性有机功能材料的应用。

    A high yield synthesis of 1,2-dihydropyrimidines by the Rh(II)-catalyzed reaction of diazocarbonyl compounds with 1,4-di- and 1,4,5-trisubstituted pyrazoles is reported. This reaction represents the first example of a carbenoid insertion into a N–N bond and provides a novel approach to 4-unsubstituted 1,2-dihydropyrimidines with a broad range of functional group tolerance. According to DFT calculations

    The palladium-catalysed direct arylation of pyrazoles with aryl halides, using PdCl(C3H5)(dppb)/KOAc catalyst, reveals a similar reactivity of C4 and C5 CH bonds of pyrazoles, whereas the C3 CH bond is almost unreactive, and gives access in one step to a variety of 4,5-diarylpyrazoles. This CH bond functionalisation reaction tolerates a variety of substituents on the aryl bromide such as nitro, cyano

    the base and DMAc as the solvent, promotes the 5-arylation in moderate to high selectivities and yields. A wide variety of aryl and heteroaryl bromide derivatives have been successfully employed. Their electronic and steric properties also have an influence on the regioselectivities and yields of the coupling products. Both electron-poor and electron-rich aryl bromides gave satisfactory results, although

    cross-couplings of nitroarenes and heteroarylboronate esters has been developed. A number of heterobiaryl compounds containing pyridine, pyrimidine, quinoline, furan, thiophene, and pyrazole were prepared using [Pd(cinnamyl)Cl]2/2-aryl-5-(2,4,6-triisopropylphenyl)-2,3-imidazolylidene[1,5-a]pyridines as the catalysts in good to excellent yields. The synthetic practicality of this approach is demonstrated through
