nzoic acid, were prepared by condensation of anthranilic acid with corresponding naturally occurring carbonyl compounds (anisaldehyde, benzaldehyde, cinnamaldehyde, citral, citronellal, cuminaldehyde, veratraldehyde, acetophenone, and α-ionone) employing conventional and microwave irradiation methods. These compounds were characterized with the aid of elemental and spectral (FT-IR, 1H NMR, and 13C
摘要 九种有气味的席夫碱,即2-(4-甲氧基苯亚甲基氨基)苯甲酸、2-(苯亚甲基氨基)苯甲酸、2-(3-苯亚丙基氨基)苯甲酸、2-(3,7-二甲基辛基-2,6-烯基氨基) ) 苯甲酸、2-(3,7-二甲基辛-6-亚亚苯基氨基)苯甲酸、2-(4-异丙基亚苄基氨基)苯甲酸、2-(3,4-二甲氧基亚苄基氨基)苯甲酸、2-(1-苯基亚乙基氨基)苯甲酸通过邻氨基苯甲酸与相应的天然存在的羰基化合物(茴香醛、苯甲醛、肉桂醛、柠檬醛、香茅醛、孜然醛、藜芦醛、苯乙酮和α-紫罗兰酮)采用常规和微波辐射方法。借助元素和光谱 (FT-IR, 1H NMR 和 13C NMR) 分析。微波辐射方法在减少反应时间、溶剂使用和增加这些化合物的产率方面是有效的,而不影响它们的嗅觉特性。这些席夫碱还表现出对各种香味组合物的嗅觉特征和对黑曲霉、产黄青霉、金黄色葡萄球菌和大肠杆菌的不同抗菌活性。图形概要 金黄色葡萄球菌和大肠杆菌。图形概要
