The reduction of a diphenyl α-iminoketone with samarium diiodide has been studied. A fast two-electron transfer gives a samarium (Z)-enamidolate, which is protonated to afford an α-aminoketone or reacted with a variety of ketones to furnish pyrrole derivatives. Possible mechanisms are proposed.

A series of 19 N‐alkyl‐diarylpyrrolyl‐acetic and ‐propionicacidderivatives was synthesized and tested. Using bovine blood as enzyme source the inhibition of cyclooxygenase and 5‐lipoxygenase, respectively, was applied to determine the antiinflammatory activity. In general all compounds tested inhibit 5‐lipoxygenase more effectively than cyclooxygenase. A structure‐activity relationship is discussed
