Title: Cross-coupling of phenolic derivatives
Usefulness: Cross-coupling of phenolic derivatives
Summary: (I) is useful as an intermediate in the synthesis of flurbiprofen (claimed), which is useful as an antiinflammatory drug.
Novelty: Preparing a cross-coupled compound, useful as an intermediate in the synthesis of flurbiprofen, comprises combining e.g. organoboron compound, an aryl alcohol derivative e.g. acylated aryl alcohol compound, and transition metal catalyst

State of Development The invention has been tested and is confirmed to work. Researchers are currently exploring the scope of substrates that can be used in the reaction. Background Synthesis of organic molecules plays a vital role in modern society: carbon-carbon and carbon heteroatom bonds are encountered in natural products, materials, drug substances and agrochemicals. There are currently methods in place for coupling phenol groups to carbon atoms, but these reactions require expensive materials and are often not efficient. Practical methods that allow for the cross coupling of phenol derivatives to carbon atoms are therefore extremely interesting, especially given their prevalence in the pharmaceutical industry.
