With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.16859-59-9,3-Hydroxyisobenzofuran-1(3H)-one,as a common compound, the synthetic route is as follows.
General procedure: 2-Formylbenzoic acid (1a; 1.0 equiv) and DMAP (0.1 equiv) were dis-solved in CH2Cl2 (0.15 M), producing a colorless clear solution. Thedesired carboxylic anhydride (2.0 equiv) and triethylamine (1.0equiv) were subsequently added and the reaction mixture was stirredat r.t. until complete conversion of the starting material was achieved(monitored by TLC). The solvent was removed under reduced pres-sure and the crude products were purified by column chromatogra-phy (n-hexane/EtOAc, 2:1)., 16859-59-9
16859-59-9 3-Hydroxyisobenzofuran-1(3H)-one 3804259, abenzofuran compound, is more and more widely used in various.
