)-1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1-carb oxylic acids and 1-methyl-4-(methylthio)-5-aroylpyrrole-2-acetic acids were synthesized and assayed as antiinflammatory and analgesic agents. The majority of these compounds exhibit a surprisingly low level of antiinflammatory activity (rat carrageenan paw) but have considerable potency as analgesics (mouse phenylquinone writing). For example, the p-tolyl-substituted
