| titleOfInvention | A kind of 2-indolinone derivative and preparation method thereof |
| abstract | The invention discloses a 2?indolinone derivative and a preparation method thereof. The reaction mechanism is as follows: under acidic conditions, compound I reacts after being catalyzed by a catalyst to generate target compound II. Wherein R 1 is C 1 -C 6 alkyl or hydrogen, R 2 is C 1 -C 6 alkyl. Under the catalysis of a high-efficiency catalyst, the present invention utilizes a direct reaction method to directly obtain the target product 2?indolinone derivatization through a one-step reaction, and the yield of the obtained target product is high. The invention also has the advantages of mild reaction conditions and simple operation, so it is very suitable for large-scale industrial production. |
