Microwave-assisted synthesis of 1-{2-[(1-benzyl-1H-1,2,3-triazol-4-yl)methoxy]phenyl}-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)prop-2-en-1-ones and their antimicrobial activity
摘要:
A series of new (E)-1-{2-[(1-benzyl-1H-1,2,3-triazol-4-yl)methoxy]phenyl}-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)prop-2-en-1-ones (3a-3i) has been synthesized via copper-catalyzed 1,3-dipolar azide-alkyne cycloaddition reaction (CuAAC) of benzyl azide with substituted (E)-3-(3-aryl-1-phenyl-1H-pyrazol-4-yl)-1-[2-(prop-2-ynyloxy)phenyl]prop-2-en-1-ones (2a-2i). The synthesized compounds have been characterized by their IR, H-l, C-13 NMR spectra, and mass spectroscopy data. All the compounds have been screened for antimicrobial activity.

ryl-4-pyrazolyl) chromones 4a-g have been synthesized by the oxidation of 2-hydroxychalcone analogues of pyrazole 3a-g with hydrogen peroxide (H(2)O(2)) in KOH-MeOH by Algar Flynn Oymanda (AFO) reaction. The structures of the compounds 4 were established by the combined use of (1)H NMR, IR and mass spectra. All the seven compounds were tested in vitro for their antifungal activity against three phytopathogenic
通过用过氧化氢将吡唑3a-g的2-羟基查耳酮类似物氧化(H(2)O (2))在KOH-MeOH中通过Algar Flynn Oymanda(AFO)反应。化合物4的结构通过结合使用(1)1 H NMR,IR和质谱确定。体外测试了所有这七个化合物对三种植物病原真菌(蠕虫属,尖孢镰刀菌和链格孢菌)的抗真菌活性。五种化合物4a,4b,4c,4e和4f与市售抗真菌化合物Actidione(环己酰亚胺)相比,对所有三种植物病原真菌的抗真菌活性均高得多。
