Electric Literature of 7477-63-6, These common heterocyclic compound, 7477-63-6, name is 7-Chloroisatin, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A mixture of 1 (0.4 mmol), 2 (0.4 mmol), Na2CO3 (0.8 mmol) and TBHP (0.4 mmol) in DMF (4 mL) was stirred at rt for 2 h. Then, the mixture was poured into ice-water, acidified with 1 N HCl aq. (6 mL). The mixture was extracted with ethyl acetate (20 mL x 3). The combined organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by silica gel flash column chromatography to give desired products..
Statistics shows that 7-Chloroisatin is playing an increasingly important role. we look forward to future research findings about 7477-63-6.
