FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES 3. THE REACTION OF 5-ARYL-2,3-DIHYDROFURAN-2,3-DIONES WITH ALIPHATIC AND AROMATIC NITRILES

Article abstract of DOI:10.1007/BF00486902

On reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with α-aminoisobutyronitrile, o-aminobenzonitrile, and β-anilinopropionitrile, we obtained aroylpyruvic acid N-(1-methyl-1-cyanoethyl)-, N-(o-cyanophenyl)-, and N-phenyl-N-(cyanoethyl)-amides, respectively.On reaction of 5-aryl-2,3-dihydrofuran-2,3-diones with cyanoacetamide we obtained aroylacetic acid N-(cyanoacetyl)amides, while in the case of methyleneaminoacetonitrile and p-dimethylaminobenzonitrile we obtained (6-aryl-4-oxo-2,3-dihydro-1,3-oxazin-3-yl)acetonitriles and 2-(p-dimethylaminophenyl)-6-aryl-1,3-oxazine-4-ones, respectively.
