Trifluoroacylated pyrroles and related compounds can be transformed to CF3-bearing pyrrolidines via a Pd/C-mediated hydrogenation under acidic conditions in high yields. The synthesis of several compounds of this type was considerably simplified as compared to formerly available procedures. Stereochemical aspects of the hydrogenation were studied and methods for both preparation and separation of diastereomerically
