Heterocyclic Carbon Compounds Containing A Hetero Ring Having Nitrogen And Oxygen As The Only Ring Hetero Atoms
(AREA)
Abstract
Variant of the process for obtaining amides of acids α -amino- β -oxi-carboxylic acids according to the principal patent characterized in that in the position of compounds of the general formula ** -in which r represents an alkyl residue with at most 4 carbon atoms or a phenyl radical1 a hydrogen atom or an alkyl radical with at most 4 carbon atoms and r2 represents a phenyl residue optionally substituted by a low molecular weight alkoxy residue or a low molecular weight carbalkoxy group, where r1 and r2 are also represented in common with the nitrogen atom the members of a saturated heterocyclic ring system are routinely introduced in place of an isonitroso group and an arylazo group and the amides obtained from α -arylazo- β -ketocarboxylic acids are further processed according to the procedure of the main patent.
