A method for the synthesis of substituted 3-amino-2-(organylsulfinyl)thieno[2,3-b]pyridines by the Thorpe—Ziegler intramolecular cyclization of substituted 3-cyano-2-[(organyl-sulfinyl)methylthio]pyridines was proposed. 3-Amino-2-(organylsulfonyl)thieno[2,3-b]pyridines were obtained by reactions of substituted 3-cyanopyridine-2-thiones with chloromethyl organyl sulfones. The reaction intermediates
一种通过取代 3-氰基-2-[(有机亚磺酰基)甲硫基]吡啶的 Thorpe-Ziegler 分子内环化合成取代的 3-氨基-2-(有机亚磺酰基)噻吩并[2,3-b]吡啶的方法是建议的。3-氨基-2-(有机磺酰基)噻吩并[2,3-b]吡啶通过取代的3-氰基吡啶-2-硫酮与氯甲基有机砜的反应获得。反应中间体3-氰基-2-[(有机基磺酰基)甲硫基]吡啶转化为3-氨基-2-(有机基磺酰基)噻吩并[2,3-b]吡啶。
