    名称:
    From 4,5,6,7-tetrahydroindoles to 3- or 5-(4,5,6,7-tetrahydroindol-2-yl)isoxazoles in two steps: a regioselective switch between 3- and 5-isomers
    摘要:
    由4,5,6,7-四氢吲哚与芳香酰基(杂环芳酰基)溴代炔烃或乙基溴代丙二烯酸酯在K₂CO₃存在下进行交叉偶联反应,可合成出带有4,5,6,7-四氢吲哚-2-基的炔烃。这些炔烃能选择性地与羟胺环化,生成3-或5-(4,5,6,7-四氢吲哚-2-基)异噁唑,这取决于反应混合物的酸性:在醋酸存在下,主要生成3-异构体(约100%选择性),而在中性条件下,则转向生成5-异构体(94-97%选择性)。 ©2014 Elsevier Ltd.出版。

    Easy way to ene‐1,1‐diamines: 1‐Haloalkynes react with secondary aliphatic amines to selectively give ene‐1,1‐diamines under the reported protocol. Single‐crystal X‐ray diffraction analysis of one of the products and its corresponding protonated form – amidinium salt – reveals structural changes occurring upon protonation of those carbon bases.

    72% yield) by the cyclocondensation of easily available 2-(acylethynyl)pyrroles with diethyl aminomalonate hydrochloride has been developed. The reaction proceeds under reflux in MeCN (6 h) in the presence of Cs2CO3. Under the same conditions, 2-(acylethynyl)pyrroles with bulky (benzyl and octyl) substituents at nitrogen atom react with diethyl aminomalonate to afford 1H,2′H-2,3′-bipyrroles and pyrrolyl-aminopyrones

    intermediates, (Z)-2-bromo-2-(pyrazol-1-yl)enones. This unexpected 2:1 coupling is in contrast to similar reactions of pyrroles, furans and thiophenes, which give the corresponding acylethynyl derivatives. This reaction opens a one-pot route to inaccessible gem-dipyrazolylenones, which have potential applications as bidentate chelating ligands and building blocks for drug design.

    An efficient method for the synthesis of pharmaceutically prospective pyrrole–aminopyrimidine ensembles (in up to 91% yield) by the cyclocondensation of easily available acylethynylpyrroles with guanidine nitrate has been developed. The reaction proceeds under heating (110–115 °C, 4 h) in the KOH/DMSO system. In the case of 2-benzoylethynylpyrrole, the unexpected addition of the formed pyrrole–aminopyrimidine as N- (NH moiety of the pyrrole ring) and C- (CH of aminopyrimidine) nucleophiles to the triple bond is observed.
