bromopyrazole 6a/6b pyrazole-1-carboxylate 8, pyridinylmethanone 9, nicotinonitrile 10, pyrazolopyridine 11a/11b, pyran-3-carbonitrile 12/13, chromenopyridine 14 and N-butyrylpyrazolyl-1-butanone 15 derivatives. The structures of the synthesized compounds were elucidated based on IR, NMR and mass spectral analyses. Group of the newly synthesized compounds were screened for their anti-diabetic activities
通过与1,2的迈克尔型加成反应合成了各种有趣的杂环骨架;1,3-二齿氮和碳亲核体。环加成不同的α,β-不饱和体系可得到溴嘧啶酮3/5,溴噻嗪4和溴吡唑6a / 6b吡唑-1-羧酸酯8,吡啶基甲酮9,烟腈10,吡唑并吡啶11a / 11b,吡喃-3-甲腈12/13,铬吡啶14和N-butyrylpyrazolyl-1-butanone 15衍生物。基于IR,NMR和质谱分析阐明了合成化合物的结构。筛选了一组新合成的化合物的抗糖尿病活性,而化合物8和11b在微摩尔浓度下针对α-葡萄糖苷酶抑制剂表现出有希望的抗糖尿病活性,IC50值在13.80-500μM之间。
