| Abstract: | Summary N-Cyano-S-methyl-isothio-ureases (1) react with  -halogen ketones (2) by ring closure yielding the (3H-oxazol-2-yliden)-cyanamides3. by ring transformation, 2-Alkoxy-5-amino-1-phenyl-3H-imidazol-4-yl)-ketones (4) are formed. Primary and secondary amines react with3 to give 2-N-alkylated (2,5-Diamino-1-phenyl-3H-imidazol-4-yl)-ketones. |
| Keywords: | (2-Alkoxy-5-amino-imidazol-4-yl)-ketones N-Cyano-S-methyl-isothioureases (2 5-Di-amino-imidazol-4-yl)-ketones |
