  • One-pot synthesis of unsymmetrical biaryls from suitably functionalized 2H-pyran-2-ones through carbanion-induced ring-transformation reactions

    An innovative synthesis of unsymmetrical biaryls (2,6) with electron-acceptor and electron-donor substituents through carbanion-induced C–C bond formation from 6-aryl-3-cyano-4-methylthio-2H-pyran-2-ones (1) and 4-sec-amino-6-aryl-2H-pyran-2-ones (5), using aliphatic ketones as a source of carbanion, is delineated and illustrated. However, a reaction of pyran-2-ones (1) with aromatic ketones failed to yield any desired product and in lieu a new compound isolated was characterized as the corresponding (4,6-diarylpyran-2-ylidene)acetonitrile (3). The structure of two representative compounds 5h and 6q has been confirmed by single-crystal X-ray diffraction analysis.
    一种创新的非对称双联苯(2,6)合成方法,通过碳负离子引发的C-C键形成,将电子受体和电子供体取代基引入6-苯基-3-氰基-4-甲硫基-2H-吡喃-2-酮(1)和4-二级氨基-6-苯基-2H-吡喃-2-酮(5),并使用脂肪酮作为碳负离子源,该方法得到了详细阐述和图解。然而,吡喃-2-酮(1)与芳香酮的反应未能产生预期产物,反而分离出一种新化合物,其特征为相应的(4,6-二苯基吡喃-2-亚基)乙腈(3)。通过单晶X射线衍射分析,两个代表性化合物5h和6q的结构得到了确认。
