3484-35-3, 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. 3484-35-3, name is 5-Methylindolin-2-one belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To a solution of appropriate oxindole (8a-e, 0.3 mmol) in ethanol (3 mL) was addedcorresponding aldehyde (12a-h, 0.32 mmol) and a catalytic amount of piperidine. The reactionmixture was stirred at reflux for 6-12 h (monitored by TLC). After cooling, the precipitate wasfiltered, washed with cold ethanol, and dried in air to furnish pure (Z)-3-(4′-(aminoalkoxy)-3′-methoxybenzylidene)indolin-2-one title compounds of formula (5a-t) as yellow/brown/orangesolids in moderate to excellent yields.
The synthetic route of 5-Methylindolin-2-one has been constantly updated, and we look forward to future research findings.
