ABSTRACT:
A process for the production of 5-alkyl tetramic acids from 4-alkoxy-3-pyrrolin-2-ones and aldehydes or ketones. By basic catalysis, 5-alkylidene-4-alkoxy-3-pyrrolin-2-ones are first formed, which are converted into the target compounds by cleavage of the alkoxy group and catalytic hydrogenation.
