nickel-catalyzed C–Htrifluoromethylation for the synthesis of trifluoromethylated freeanilines using Togni’s reagent has been developed. This approach exhibits a good functional group tolerance, good regioselectivity, and chemoselectivity under mild conditions. The newly developed economical one-step method is a better alternative to synthesize trifluoromethylated freeanilines.

Disclosed is a series of materials, which exhibit large birefringence under the influence of an applied electric field. These materials are capable of switching this large birefringence with a characteristic time on the order of 1 microsecond or less. In addition, these materials have good optical loss at this wavelength, and are stable under irradiation. These materials are suitable for fabrication of optical devices such a variable optical attenuators, switches, and modulators that respond in these time frames or slower. These materials are also suitable for use across a wide range of wavelengths. As a second component of this invention, some of these novel materials exhibit these desired optical properties (large birefringence, low loss, stability under illumination) at wavelengths as short as about 400 nm. These materials are suitable for fabrication of optical devices operating at or about 405 nm, where conventional EO materials strongly absorb and/or quickly degrade.

The present invention provides novel conformationally-defined macrocyclic compounds that have been demonstrated to be selective modulators of the ghrelin receptor (GRLN, growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and/or variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as antagonists or inverse agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, obesity and obesity-associated disorders, appetite or eating disorders, addictive disorders, cardiovascular disorders, gastrointestinal disorders, genetic disorders, hyperproliferative disorders, central nervous system disorders and inflammatory disorders.
Herein we report a highly para-selective C–H olefination of anilinederivatives by a Pd/S,O-ligand-based catalyst. The reaction proceeds under mild reaction conditions with high efficiency and broad substrate scope, including mono-, di-, and trisubstituted tertiary, secondary, and primary anilines. The S,O-ligand is responsible for the dramatic improvements in substrate scope and the high para-selectivity
