Synthesis of structurally diverse diarylketones through the diarylmethyl sp3 CH oxidation
摘要:
Under open-flask conditions, an efficient method to assemble a series of diversely functionalized diarylketones in the presence of commercially available NBS has been developed. Yields of up to 99% have been achieved employing diarylmethanes as starting material. Based on O-18-labeled experiment, the addition of stoichiometric water eventually leads to excellent yields in all carbonylation cases. (C) 2014 Elsevier Ltd. All rights reserved.

Compounds of the structure ##STR1## wherein Z is selected from optionally substituted thienyl, thiazolyl, oxazolyl and furyl are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states.
The invention relates to a process for synthesising organic molecules. The invention provides a process for forming an sp2-sp3carbon-carbon bond between a first compound comprising a substituted or unsubstituted aromatic group and a second compound comprising a substituted or unsubstituted aromatic group in the presence of a catalyst, water, and a first base. The process may find use in the preparation of active pharmaceutical ingredients.
