The design and synthesis of functionalized isoindigo compounds by reaction of isoindigo with (S)-glycidyl tosylate, epibromohydrin, 2-(bromomethyl)-1-(arylsulfonyl)aziridine, and 2-(bromomethyl)-1-(alkylsulfonyl)aziridine in the presence of MeONa proceed under mild conditions in moderate yields. (3Z,3’Z)-3,3’-(Ethane-1,2-diylidene)bis(1-(oxiran-2-ylmethyl)indolin-2-one), with an extended central olefin
通过异靛蓝与 (S)-甲苯磺酸缩水甘油酯、表溴醇、2-(溴甲基)-1-(芳基磺酰基)氮丙啶和 2-(溴甲基)-1-(烷基磺酰基)氮丙啶反应设计和合成功能化异靛蓝化合物MeONa 的存在在温和条件下以中等产率进行。(3Z,3'Z)-3,3'-(Ethane-1,2-diylidene)bis(1-(oxiran-2-ylmethyl)indolin-2-one),具有扩展的中心烯烃 π-共轭部分是也与甲基-环氧乙烷反应得到相应的 N,N'-二取代衍生物。具有各种吸电子取代基(包括氮丙啶、环氧乙烷、腈、羰基和磺酸盐)的假设异靛-噻吩 DA 分子的 DFT 和 TD-DFT 计算表明,官能团的接近度和强度对 HOMO 有显着影响, LUMO,垂直激发能,
