Adding a certain compound to certain chemical reactions, such as: 2058-72-2, name is 5-Bromo-1-methylindoline-2,3-dione, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 2058-72-2, category: indolines-derivatives
General procedure: A mixture of corresponding compound 1(0.5 mmol), isatin 3 (0.5 mmol), and sarcosine (0.5 mmol) in acetonitrile (40 mL) (for 1a-c) or in amixture of acetonitrile (30 mL) and chloroform (10 ml) (for 1d-f) was refluxed with stirring for 36 or 72 h for starting compounds 1a-c and 1d-f, respectively. Then the reaction mixture was cooled to room temperature, the precipitate of compounds 4a-e,j,o was filtered off and washed with acetonitrile and water. The reaction mixture of compounds 4f-i,k-n,p-t was concentrated on a rotary evaporator to half of an original volume. After cooling, the precipitate was filtered off and washed with water. Recrystallization from acetonitrile or methanol (4n) gave dispirocompounds 4a-t.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Bromo-1-methylindoline-2,3-dione, other downstream synthetic routes, hurry up and to see.
