These common heterocyclic compound, 1168150-46-6, name is (E)-Methyl 3-(methoxy(phenyl)methylene)-2-oxoindoline-6-carboxylate, 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. 1168150-46-6
General procedure: A mixture of intermediate (3a, 3b, 6a, 6b, 10a, 10b, 11a-d, and14a-g, 1.5 mmol) and methyl (E)-3-(methoxy(phenyl)methylene)-2-oxoindoline-6-carboxylate (1.5 mmol) in methanol (10 mL) wasstirred under reflux for 5-10 h. When TLC showed the completionof the reaction, the solution was cooled to room temperature. Theprecipitate was filtered off to give a crude product, which wasrecrystallized from methanol to provide the target compounds.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1168150-46-6.
