A modified procedure of the selective cleavage of three of the pentyloxy groups from 2,3,6,7,10,11-hexapentyloxytriphenylene (1) to give C3-symmetric 2,6,10-trihydroxy-3,7,11-tripentyloxytriphenylene (2) is described. The methodology has been extended to provide a convenient route to the C3-symmetric triphenylene derivative 8, with orthogonally protected carboxylic acid groups.
本文描述了一种改良的从2,3,6,7,10,11-六戊氧基三苯基(1)中选择性裂解三个戊氧基团得到C3-对称2,6,10-三羟基-3,7,11-三戊氧基三苯基(2)的方法。该方法已被扩展为一种制备C3-对称三苯基衍生物8的便捷途径,其中羧酸基团具有正交保护。
