The present invention provides an improved process for preparing an hydroxycarbamoyl derivative of a carboxylic acid using a hydroxylammonium salt of a carboxylic acid as a reagent.
A novel series of MMP inhibitors has been identified. The compounds are potent selective inhibitors of collagenase with good solubility and oral bioavailability. One compound, designated Ro32-3555, has been selected for development as a cartilage protective agent for use in the treatment of rheumatoid-and osteoarthritis. (C) 1997 Elsevier Science Ltd.

A short synthesis, based on a succinate acylation-akylation-decarboxylation approach, of the clinical compound Ro 32-3555 is reported. The nature of the selectivity in the mono-alkylation of succinates was examined under varying enolization conditions and in the presence of chaotropic additives. (C) 1998 Elsevier Science Ltd.
