We report a convenient and efficient synthesis of indeno[1,2-c]pyrazol-4(1H)-ones (4a‒o) by the reaction of a variety of 2-acyl-(1H)-indene-1,3(2H)-diones (1) and 2-hydrazinylbenzo[d]thiazole/2-hydrazinyl-6-substitutedbenzo[d]thiazoles (2) in the presence of glacial acetic acid in good yields. The structure of the compounds thus prepared were confirmed by analytical and spectral (FT-IR, 1H NMR, 13C
我们报告了通过各种2-酰基-(1 H)-茚-1的反应,方便高效地合成茚并[1,2 - c ]吡唑-4(1 H)-ones(4a‒o),在冰乙酸存在下,以高收率得到3(2 H)-二酮(1)和2-肼基苯并[ d ]噻唑/ 2-肼基-6-取代的苯并[ d ]噻唑(2)。通过分析和光谱(FT-IR,1 H NMR,13 C NMR和HRMS)技术确认了由此制备的化合物的结构。所有合成的茚并[1,2 - c ]吡唑-4(1 H)-ones(4a‒o通过使用阿卡波糖(Acarbose)作为标准药物测定其体外II型糖尿病抑制活性,并以链霉素和氟康唑为参考药物测定其体外抗菌活性。在合成的衍生物中,发现4e(IC 50 = 6.71μg/ mL)与标准阿卡波糖(IC 50 = 9.35μg/ mL)和4i(IC 50 = 11.90μg / mL)相比,对α-葡萄糖苷酶的抑制作用更强。与标准阿卡波糖(IC
