Electric Literature of 56341-37-8, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 56341-37-8, name is 6-Chlorooxindole belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 30a E/Z-6-Chloro-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one To the mixture of 6-chlorooxindole (16.2 g, 92 mmol) (Crescent) and 3-chlorobenzaldehyde (12.9 g, 92 mmol) (Aldrich) in methanol (109 mL) was added pyrrolidine (6.55 g, 92 mmol) (Aldrich) dropwisely. The mixture was then heated at 70 C. for 3 hours. After cooling to 4 C., the resulting precipitate was collected and dried to give E/Z-6-chloro-3-(3-chloro-benzylidene)-1,3-dihydro-indol-2-one as a bright yellow solid. (Yield 25.2 g, 95%).
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, 6-Chlorooxindole, other downstream synthetic routes, hurry up and to see.
