Abstract:
Provided is a process for the preparation of diaryl oxide compounds. The process uses a mixed metal oxide catalyst containing oxides of aluminum and magnesium to decarboxylate a diaryl carbonate compound to yield the diaryl oxide compound.
Abstract:
The present invention relates to a chemical genus of 3-(triaryl)-2-aminopropanol derivative inhibitors of LTA4H (leukotriene A4 hydrolase) useful for the treatment and prevention of inflammatory diseases and disorders.
Abstract:
The present invention comprises novel aromatic molecules, which can be used in the treatment of pathological conditions, such as cancer, skin diseases, muscle disorders, and immune system-related disorders such as disorders of the haematopoietic system including the haematologic system in human and veterinary medicine.
Abstract:
The invention relates to the use of cyclovinyl phosphine compounds in the form of complexes with copper, as catalysts for reactions leading to the formation of carbon-carbon and carbon-heteroatom bonds. The invention also relates to complexes of copper with at least one cyclovinyl phosphine, as well as to the method for creating a carbon-carbon or a carbon-heteroatom bond catalysed by a cyclovinyl phosphine/copper complex.
