The paper describes the synthesis and antimicrobial (antileishmanial, antibacterial and antifungal) activity of some classical hydrazones of benzophenones and of 1,2-diketones. N-(Diaryl) acyl derivatives of these hydrazones have also been synthesized and evaluated. 4,4,-Demthoxybenzil monohydrazone and 4,4′-dimethoxybenzophenone hydrazone showed significant antileishmanial activity. The effect of

α-diaryl-β-alkynol derivatives in water at room temperature was developed using the cocatalysis of a Lewis acid and meso-tetraphenylporphyrin iron(III) chloride (FeTPPCl). The unprecedented transformation was promoted by a modulation of the charge properties of propargylic carbocation chemistry and the use of an in situ-generated oxonium ylide as a matching nucleophile. The reaction was performed in

The paper describes the synthesis, characterization data, and biological activity (antibacterial, antifungal, and brineshrimpslethality) of new azetidin‐2‐ones. The compounds have been synthesized by the reaction of diarylketenes, generated in situ from thermal decomposition of the 2‐diazo‐1,2‐diarylethanones, with N‐(1‐methyl‐1H‐indol‐3‐yl)methyleneamines. The compounds have been characterized by
本文描述了新的azetidin-2-one的合成,表征数据和生物学活性(抗菌,抗真菌和盐水虾致死性)。这些化合物是由二芳基酮与2- N-(1-甲基-1 H-吲哚-3-基)亚甲基胺热分解而合成的,这些化合物是由二芳基1,2-二芳基酮的热分解而原位生成的。该化合物已通过元素分析和光谱(IR,1 H和13 C NMR和MS)数据进行了表征。该论文还报告了这些化合物的抗菌,抗真菌和盐水虾杀伤力测定结果。一些化合物表现出显着的生物学活性。
