    摘要:
    An efficient protocol for the assembly of a new series of 1,3-disubstituted 4,5-bis(trifluoromethyl)-1H-pyrazoles - through a concise sequential iodination-trifluoromethylation reaction at the C-4 position of an initial series of 1-aryl-3-(alkyl/aryl)-5-trifluoromethyl-1H-pyrazoles (electronically deactivated heterocycles), using NIS and MFSDA, at good conversion yields and in short reaction times - is reported.

    摘要:
    我们报告了4-三氟甲基,4-二氟甲基-和4-单氟甲基sydnones的合成和一些结构研究。除后者以外的所有化合物都是稳定的,并且在与炔烃进行环加成反应后,代表了一系列吡唑的有效前体。尽管我们已经观察到Bn取代的sydnones可以提供意想不到的炔烃插入模式以生成3-氟甲基异构体,但是环加成物通常具有高度的区域选择性并提供5-氟甲基吡唑产物。

  • A General and Regioselective Synthesis of 5-Trifluoromethyl-pyrazoles
    作者:Robert S. Foster、Harald Jakobi、Joseph P. A. Harrity
    DOI:10.1021/ol3021918
    日期:2012.9.21
    Two synthetic approaches to 4-trifluoromethylsydnones, a novel class of these mesoionic reagents, are reported. These compounds undergo regioselective alkyne cycloaddition reactions, thereby providing a general approach to 5-trifluoromethylpyrazoles. This method has been employed in a short formal synthesis of the herbicide fluazolate.

  • Solvent- and Transition Metal Catalyst-Dependent Regioselectivity in the [3+2] Cyclocondensation of Trifluoromethyl<i>-</i>α,β<i>-</i>ynones with Hydrazines: Switchable Access to 3- and 5-Trifluoromethylpyrazoles
    作者:Min-Tsang Hsieh、Sheng-Chu Kuo、Hui-Chang Lin

    日期:2015.3.9
    The regioselectivity of the [3+2] cyclocondensation of trifluoromethyl‐α,β‐ynones with hydrazines can be readily tuned to preferentially afford either 3‐ or 5‐trifluoromethylpyrazoles through variation of the reaction conditions. Under catalysis with copper(II) acetate (2.0 mol%), cyclocondensation proceeded smoothly to yield 3‐trifluoromethylpyrazoles with high regioselectivity. In contrast, when
    甲基组成的[3 + 2]环化缩合反应中区域选择性- α,β - ynones与类可以容易地调谐到优先得到或者3-或通过反应条件的变化5- trifluoromethylpyrazoles。在乙酸(II)(2.0 mol%)的催化下,环缩反应顺利进行,得到具有高区域选择性的3-三甲基吡唑。相反,当反应在无催化剂的条件下在二甲基亚砜中进行时,主要观察到了5-三甲基吡唑的形成。

    The regiospecific synthesis of a series of twelve 5-trifluoromethyl-4,5-dihydropyrazoles and -pyrazoles from the cyclocondesation reaction of 4-alkoxy-1,1,1-trifluoro-3-alken-2-ones [F3CC(O)CH=C(R1)OR, where R1 = Me, Et, Pr, iso-Pr, Bu, iso-Bu, Ph, H; and R = Me, Et] with phenylhydrazine in toluene by environmentally benign microwave induced techniques is reported. It is shown that under appropriated
