A new series of chalcones (3a-j) were synthesized by condensation of simple aldehydes with substituted acetophenones in presence of alkali. The resulted chalcones upon cyclization in presence of glacial acetic acid with isoniazid (INH) will yields the title compounds (4a-j). The newly synthesized compounds were assigned on the basis of IR,1H NMR, and Mass spectral data. All the final compounds were evaluated for theirin vitroantimicrobial activity.
一系列新的香豆素类化合物(3a-j)通过在碱性条件下将简单的醛和取代的苯乙酮缩合而成。得到的香豆素类化合物在冰醋酸存在下与异烟肼(INH)环化,将产生标题化合物(4a-j)。这些新合成的化合物根据红外光谱、核磁共振和质谱数据进行了鉴定。所有最终的化合物都被评估其体外抗菌活性。
