| Abstract: | Reaction of equivalent amounts of alkyl 4-aminophenylacetates with maleic anhydride gave rise to the corresponding alkyl 4-N-maleimidophenylacetates which with diethylamine, piperidine, and morpholine afforded esters of 4-(3-dialkylamino-2,5-dioxo-2,3,4,5-tetrahydro-1H-pyrrolyl)phenylacetic acids as stereoisomer mixtures. |
