visible‐light‐mediated carbonylative amidation of aryl, heteroaryl, and alkyl halides. A tandem catalytic cycle of [Ir(ppy)2(dtb‐bpy)]+ generates a potent iridium photoreductant through a second catalytic cycle in the presence of DIPEA, which productively engages aryl bromides, iodides, and even chlorides as well as primary, secondary, and tertiary alkyl iodides. The versatile in situ generated catalyst is compatible

The present invention discloses methods for producing a carboxylic acid chloride compound which comprises the step of reacting an alkyl-substituted cyclohexyl carboxylic acid with a chlorinating agent in the presence of a specific urea compound. According to this invention, it is possible to produce a carboxylic acid chloride compound which has high reaction speed, and whose product has high purity or high yield. Thus produced carboxylic acid chloride compound is useful as an intermediate for producing D-phenylalanine derivatives which are used as agents for treating diabetes.

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.
The application relates to phenyl- or naphthylsulfonamide derivatives of the structural formula (I). The compounds are described as inhibitors of USP30 (ubiquitin specific peptidase 30) useful for the treatment of conditions involving mitochondrial defects including neurodegenerative diseases such as Alzheimer's and Parkinson's or a neoplastic disease such as leukemia.
