Discovery of (E)-Methyl 3-(methoxy(phenyl)methylene)-2-oxoindoline-6-carboxylate

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1168150-46-6, name is (E)-Methyl 3-(methoxy(phenyl)methylene)-2-oxoindoline-6-carboxylate, A new synthetic method of this compound is introduced below., 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.

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
