Ethyl-2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (1) as a precursor derivative was used for the synthesis of variable heterocyclic compounds through its reactions with different reagents such as 9-anthraldehyde, 4-acetylbiphenyl, ethyl chloroacetate, ethyl benzoylacetate, chloroacetonitrile and diethyl malonate. Both conventional thermal and microwave irradiation techniques were used
Ethyl-2-amino-4,5,6,7-tetrahydrobenzo[ b ]thiophene-3-carboxylate ( 1 ) 作为前体衍生物,通过与 9-anthraldehyde 等不同试剂的反应,合成了多种杂环化合物,4-乙酰联苯,氯乙酸乙酯,苯甲酰乙酸乙酯,氯乙腈和丙二酸二乙酯。合成过程中使用了传统的热辐射和微波辐射技术。使用不同的分析和光谱工具,如 IR、 1 H-、13 C-NMR 以及质谱法,阐明了所得衍生物的分子式和结构。观察到产品的可变结构特征。1的结构和晶面分析也从 X 射线衍射和 Hirshfeld 研究中获得。所报道化合物的能量优化结构通过密度泛函理论 (DFT/B3LYP) 进行,基组为 6-31 G 和双 zeta 加极化 (d,p)。计算了量子反应描述符并将其与其生物学特性相关联。分析了报告的衍生物的抗菌和细胞毒性抑制作用。还研究了化合物的分子
