1127-59-9, 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. 1127-59-9, name is 7-Methylindoline-2,3-dione, A new synthetic method of this compound is introduced below.
General procedure: Mg(ClO4)2 (10 mol percent) was added to a mixture of isatin (2 mmol), malononitrile or ethyl cyanoacetate (2mmol), and dimedone (2 mmol) in aqueous ethanol solution(50percent, v/v, 5 mL), and the resulting mixture was stirred at 50¡ãC for 30-60 min. Upon completion of the reaction (TLC),the mixture was allowed to cool to room temperature. The resulting solid was filtered and washed successively with water (2 ¡Á 30 mL) and cold aqueous ethanol (2 ¡Á 1 mL) to afford pure product 4.
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.
