Title:
SYNTHESIS OF PYRAZOLE BY COUPLING BETWEEN CARBOXYLIC ACID DERIVATIVE AND ENAMINE
Document Type and Number:
Japanese Patent JP2013159610
Kind Code:
A
Abstract:
To improve a method of synthesizing pyrazole using coupling between a carboxylic acid derivative and enamine under oxidation conditions.
In a novel method of synthesizing pyrazole, pyrazole is synthesized when enamine is oxidatively converted using a suitable N-containing carboxylic acid derivative in the presence of copper ions and a 2-picolinic acid derivative.
