Adding a certain compound to certain chemical reactions, such as: 1127-59-9, name is 7-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 1127-59-9, Formula: C9H7NO2
General procedure: Compound B (11.9 mg, 0.02 mmol) was added at 4 C in a mixed solution of Eosin 1a (29.4 mg, 0.2 mmol) and methyl acetoacetate 2a (107.8 muL, 1.0 mmol) in tetrahydrofuran (1.0 mL). The reaction was stirred at 4 C for 96 hours. Spin-drying, column chromatography (petrole ether: ethyl acetate = 1 : 1-1 : 2), and evaporated to give a pale yellow amorphous solid 49.0mg, yield 93%, 90% ee.
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, 7-Methylindoline-2,3-dione, other downstream synthetic routes, hurry up and to see.
