A highly efficient, microwave-assisted, regioselective synthesis of 2,3-disubstituted-6-arylpyridines and new series of 7,7-dimethyl-2-aryl-5,6,7,8-tetrahydroquinoline-5-ones from enaminones in the presence of K5CoW12O40.3H2O (1.0 mol %) as heterogeneous catalyst under solvent free conditions is reported.
高效的微波辅助区域选择性合成的2,3-二取代的6-芳基吡啶和新的7,7-二甲基2-芳基5,6,7,8-四氢喹啉5-酮从氨基酮中合成。据报道在无溶剂条件下存在K 5 CoW 12 O 40 .3H 2 O(1.0 mol%)作为非均相催化剂。
