Abstract
The objective of this study is to synthesize a number of oximes along with their terphthaloyl oxime esters derived from acetophenone, 4-methylacetophenone, 4-hydroxyacetophenone, 4-aminoacetophenone and 4-nitroacetophenone as a part of ongoing research. Five acetophenone oximes have been synthesized by refluxing the acetophenone derivative with a solution of hydroxylamine hydrochloride in the presence of potassium hydroxide. The corresponding acetophenone oximes were obtained as solid materials in moderate to good yields. The structures of the resulting oximes were confirmed using IR, NMR and mass spectrometer. The HNMR data revealed that one oxime of the synthesized oximes was obtained as a mixture of two E/Z isomers in a ratio of (8:1). These resulting oximes were subjected into an esterification process with the terphthaloyl chloride in molar ratio of (1:2) respectively. The esterification reaction was carried out under basic conditions at 0 – 5 ºC then room temperature. The five corresponding bridged terphthaloyl oxime esters have been formed as solid materials in moderate yields. The structures of the obtained terphthaloyl esters were also confirmed by spectroscopic techniques such as IR, NMR and mass spec.
Highlights
The plants are frequently infected by different pathogenic fungal, bacterial and viral which result in significant loss to crops [1]
White mold disease in bean is caused by fungi, Sclerotinia sclerotiorum, resulting in significant decrease in produced crop [17,18,19]
Our study aims to 1) assess the antifungal potent of some metallic NPs against S. sclerotiorum on common bean plants under different conditions
Summary
The plants are frequently infected by different pathogenic fungal, bacterial and viral which result in significant loss to crops [1]. In recent years, engineering nanomaterials (ENMs) have been practically increased, attributed to their physico-chemical characteristics, which significantly differ than their bulk forms [3] Some metallic NPs of SiO2, MgO, and ZnO are able to destroy pathogenic fungi and inhibit their released toxins [7]. Another investigation demonstrated that, MgO was potential inhibitor to growth of fungi; Fusarium and Aspergillus flavus species [8]. Our study aims to 1) assess the antifungal potent of some metallic NPs against S. sclerotiorum on common bean plants under different conditions. Our study aims to 1) assess the antifungal potent of some metallic NPs against S. sclerotiorum on common bean plants under different conditions. 2) To assay the biochemical alterations and metal accumulation in edible part after storage condition
