1,4-naphthoquinone 2-iminothiazole hybrids were synthesized via a cyclization reaction of 2,3-diaminonaphthalene-1,4-dione N -aroylthioureas and α-bromoketones in good to excellent yields (74–94%). The stereochemistry of one of the 1,4-naphthoquinone 2-iminothiazole products was characterized by single crystal X-ray diffraction technique. Photophysical properties of the compounds in DMSO, HAc and THF
摘要 在本文中,通过 2,3-二氨基萘-1,4-二酮 N-芳酰基硫脲和 α-溴酮的环化反应合成了一系列新型高度官能化的 1,4-萘醌 2-亚氨基噻唑杂化物,收率良好至极好。 (74–94%)。1,4-萘醌 2-亚氨基噻唑产品之一的立体化学通过单晶 X 射线衍射技术表征。化合物在 DMSO、HAc 和 THF 中的光物理性质通过紫外-可见光谱法测定。还使用密度泛函理论 (DFT) 和瞬态 DFT (TD-DFT) 在 B3LYP/631 + g(d,p) 理论水平上确定了化合物的基态几何形状和吸收光谱。计算结果与实验值一致。对各种细菌(金黄色葡萄球菌、B. subtilis、A. hydrophila、E. coli 和 A. baumannii)、真菌(C. glabrata C.tropicals 和 C. albicans)和分枝杆菌(M.tuberculosis H37Rv)菌株。这
