cyanothioacetamide and cyanoacetamide under solvent-free conditions at 25 °C to give pyridine-2(1H)thione/one derivatives in excellent yields. These compounds were further reacted by grinding with different halogenated reagents to give 2-S/O-alkyl pyridine derivatives. The latter compounds were utilized for the synthesis of thieno[2,3-b]pyridine, pyrazolopyridine, pyridothienopyrimidine and pyridothienooxazinone
4,4,4-Trifluoro-1-(thiophen-2-yl)butane-1,3-dione 通过与氰硫代乙酰胺和氰基乙酰胺在 25 °C 无溶剂条件下研磨反应得到吡啶-2(1H) 硫酮/one 衍生物以优异的产量。这些化合物通过与不同的卤化试剂研磨进一步反应,得到 2-S/O-烷基吡啶衍生物。后一种化合物用于合成噻吩并[2,3-b]吡啶、吡唑并吡啶、吡啶并噻吩并嘧啶和吡啶并噻吩并恶嗪酮衍生物。
