| titleOfInvention | Method for preparing 2-oxindole and N-hydroxy-2-oxindole |
| abstract | (57) [Summary]nThe present invention provides a practical method for preparing 2-oxindole, N-hydroxy-2-oxindole, or a mixture thereof, comprising the steps of: contacting 2-nitroarylmalonic diester Hydrogenating to produce a 2- (N-hydroxyamino) arylmalonic acid diester, 2-aminoarylmalonic acid diester, or a mixture thereof as a first reaction intermediate; intramolecular aminolysis of one ester group Cyclizes the first reaction intermediate to give the N-hydroxy-2-oxindole-3-carboxylic acid ester, 2-oxindole-3-carboxylic acid ester, or a mixture thereof, And hydrolyzing and decarboxylating the remaining ester groups of the second reaction intermediate to form N-hydroxy-2-oxindole, 2-oxindole Or to form a mixture thereof, the cyclization reaction and hydrolysis and decarboxylation Here, without isolating the reaction intermediates, are performed in situ using the catalytic hydrogenation reaction. |
