2,3-二甲氧基-9H-芴-9-酮 | 2,3-dimethoxy-9H-fluoren-9-one | 2041-27-2 | C15H12O3 | 240.258 |
A novel and efficient methodology has been developed for the intramolecular aryl C–H oxidative lactonization of 2-arylbenzaldehyde using a low-cost CuCl catalyst and TBHP as the oxidant at room temperature.
The nickel-catalyzed cross-coupling of methoxyarenes was applied to buflavine, which allows for the selective monosubstitution of one of the two methoxy groups in the molecule, leading to the formation of 2- and 3-substituted isomers. Trimethylsilylmethyl (TMSCH2), phenyl, and alkynyl groups can be introduced into buflavine using this method. The resulting TMSCH2 analogue of buflavine can also be converted into several other derivatives.
镍催化的甲氧基芳烃交叉偶联反应被应用于布氟啉,这使得分子中的两个甲氧基中的一个可以进行选择性的单取代反应,从而形成2-和3-取代异构体。使用这种方法可以将三甲基硅甲基(TMSCH2)、苯基和炔基引入布氟啉中。由此产生的TMSCH2类似物还可以转化为几种其他衍生物。
