| titleOfInvention | Process for preparation of 2-oxocarboxylic acid esters |
| abstract | A process for the preparation of 2-oxocarboxylic acid esters represented by the general formula (I), characterized by oxidizing a 2-hydroxycarboxylic acid ester represented by the general formula (II) in the presence of a nitroxyl free radical represented by the general formula (II), a hypochlorite, a metal bromide, and water with the pH of the reaction system being kept within the range of 5 to 7: (II) (III) (I) wherein R1 and R2 are each optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, or optionally substituted aralkyl; and R3 is hydrogen, alkoxyl, aralkyloxy, acyloxy, or hydroxyl. |
