A new synthetic approach for introducing N-capping groups onto peptides attached to a solidsupport, combining aminocarbonylation under mild conditions using a palladacycle precatalyst and solid-phase peptide synthesis, is reported. The use of a silacarboxylic acid as an in situ CO-releasing molecule allowed the reaction to be performed in a single vial. The method also enables versatile substitution

57 Administration of an N-acylated amino acid (ornithine, lysine, phenylglycine or phenylalanine) in association with a penem or carbapenem antibiotic relieves or eliminates the renal problems associated with administration of the antibiotic alone. The amino acid and antibiotic may be formulated together as a composition or administered separately, either simultaneously or sequentially. A pharmaceutical composition may be prepared simply by mixing the two components.
