    Abstract: 5-Substituted-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carboxylic acids of the formula ##STR1## wherein Y is a moiety selected from the group consisting of ##STR2## in which R is hydrogen, methyl, chloro or bromo, the R substitution being at the 3, 4 or 5 positions of the thiophene ring,R.sup.1 is hydrogen, a lower alkyl group having 1 to 4 carbon atoms, a lower alkoxy group having from 1 to 4 carbon atoms, chloro, fluoro or bromo, the R.sup.1 substitution being at the ortho, meta or para positions of the aroyl group, andR.sup.2 is hydrogen or a lower alkyl group having from 1 to 4 carbon atoms, are prepared, by hydrolysis, from their corresponding nitriles.
