| titleOfInvention | Method for producing N-hydroxy-pyrrole-2-carboxylic acid |
| abstract | (57) [Summary] [PROBLEMS] To control the generation of high-purity N- Provided is a method for producing hydroxy-pyrrole-2-carboxylic acid and pyrrole-2-carboxylic acid at a high yield. SOLUTION: Formula: embedded image By treating a nitroketoester represented by the formula with a reducing agent: A method for producing N-hydroxy-pyrrole-2-carboxylic acid represented by the formula: [Wherein, R 1 , R 2 and R 3 independently represent a hydrogen atom, an optionally substituted alkyl, an optionally substituted aryl or an optionally substituted heteroaryl. However, R 1 and R 2 together form two adjacent R 2 and R 3 together may represent an aromatic ring that may be substituted with two carbon atoms and / or R 2 and R 3 may be substituted with a cycloalkane or substituted with two adjacent carbon atoms May represent a heterocycloalkane. R 4 represents an optionally substituted alkyl. ] |
