The present invention provides novel Ruthenium-based transition metal complex catalysts comprising specific ligands, their preparation and their use in hydrogenation processes. Such complex catalysts are inexpensive, thermally robust, and olefin selective.
A series of novel spiro-substituted glutaramide derivatives have been prepared, including the pharmaceutically acceptable salts thereof and bioprecursors therefor, wherein the spiro-substituent completes a 5- or 6-membered carbocycyclic ring and is located at the carbon atom adjacent to the carbamoyl group. These particular compounds are inhibitors of the neutral endopeptidase E.C.3.4.24.11 enzyme and are therefore useful in therapy as diuretic agents for the treatment of hypertension, heart failure, renal insufficiency and other disorders. Methods for preparing these compounds from known starting materials are provided.
