| 摘要 |
The present invention relates to 2,3-diaminoacrylonitrile derivatives or salts thereof, having the formula wherein R represents an alkyl group which may be substituted by (unsubstituted or substituted phenyl groups, halogen atoms, C1-6 alkoxycarbonyl groups, carboxy groups, C1-6 alkoxycarbonyl C1-6 alkylthio groups, hydroxy groups, mercapto groups, or heterocyclic groups containing oxygen atoms), an alkenyl group, a cycloalkyl group, an aryl group which may be substituted by (halogen atoms, C1-6 alkyl groups, cycloalkyl groups, nitro-groups, unsubstituted or substituted phenyl or phenoxy groups) or heterocyclic groups containing oxygen atoms or sulfur atoms. The 2,3-diaminoacrylonitrile derivatives can be used as starting materials for the production of pharmaceutical and/or agricultural intermediates such as cyanoimidazoles, cycnopyrazines or other cyano-substituted heterocycles. |
