density functional theory (DFT) calculations confirm the expected non-coplanarity caused by steric interactions between the 2-methoxyphenyl substituents and the methyl groups on the BODIPY core and predict a 7.46 Kcal mol−1 barrier to diastereomer conversion by rotation around the BODIPY-aryl bond. The syn isomer is predicted to be more stable than the anti-isomer by only 0.13931 Kcal mol−1. The theoretical
一种新的轴向手性BODIPY基荧光染料,4,4‒二氟‒2,6‒双(2‒甲氧基苯基)‒1,3,5,7‒四甲基‒8‒苯基‒4‒硼酸‒3a,4a‒已经合成了‒sindacene 3。通过FT-IR,1 H-NMR,13 C-NMR,19 F-NMR,质谱和元素分析确认了其分子结构。的19 F NMR谱是具有1的存在是一致的:手性,1混合物抗-diastereoisomer和内消旋,顺式异构体,其不互变对d加热至100℃ 8-甲苯。通过密度泛函理论(DFT)计算进行的几何最小化证实了2-甲氧基苯基取代基与BODIPY核上的甲基之间的空间相互作用所导致的预期非共面性,并预测了通过绕其旋转而对非对映体转化的7.46 Kcal mol -1势垒。 BODIPY-芳基键。据预测,顺式异构体比反式异构体更稳定,仅0.13931 Kcal mol -1。通过分子对接研究已经探索了本发明化合物作为抗菌剂的理论潜
