The present invention relates to a 2,3-diaminoacrylonitrile derivative or salts thereof, having the formula ##STR1## wherein R represents an alkyl group (which may be substituted by unsubstituted or substituted phenyl groups, halogen atoms, C.sub.1-6 alkoxycarbonyl groups, carboxy groups, C.sub.1-6 alkoxycarbonyl C.sub.1-6 alkylthio groups, hydroxy groups, mercapto groups, cycloalkyl groups or heterocyclic groups containing oxygen atoms); an alkenyl group; a cycloalkyl group; an aryl group (which may be substituted by halogen atoms, C.sub.1-6 alkyl groups, nitro-groups, unsubstituted or substituted phenyl or phenoxy groups or heterocyclic groups containing oxygen atoms or sulfur atoms). The 2,3-diaminoacrylonitrile derivative can be used as starting materials for the production of pharmaceutical and/or agricultural intermediates such as cyanoimidazoles, cyanopyrazines or other cyano-substituted heterocycles.
本发明涉及一种2,3-二氨基丙烯腈衍生物或其盐,其化学式为##STR1##其中R代表一个烷基(可以被未取代或取代的苯基,卤素原子,C.sub.1-6烷氧羰基基团,羧基,C.sub.1-6烷氧羰基C.sub.1-6烷硫基团,羟基,巯基,环烷基或含氧原子的杂环基团取代);烯基;环烷基;芳基(可以被卤素原子,C.sub.1-6烷基,硝基,未取代或取代的苯基或苯氧基团或含氧或硫原子的杂环基团取代)。2,3-二氨基丙烯腈衍生物可以用作制备药物和/或农业中间体的起始材料,例如氰基咪唑,氰基吡嗪或其他氰基取代的杂环化合物。
