cyclopropyl ynamide cyclization to construct fully substituted pyrroles and cyclopentadienederivatives in the presence of a gold catalyst was developed. In this version of pyrrole generation, a novel method to furnish gold vinylidenes through [1,2]-cyclopropyl migration was described. On the contrary, the production of cyclopentadienes proceeded through a proton-transfer step. These intriguing mechanisms

This invention relates to a phosphoric acid group-containing non-aqueous dispersion wherein polymer particles are dispersed in a solution of a macromolecular dispersion stabilizer dissolved in an organic solvent, said polymer particle being a particle of polymer comprising a phosphoric acid group-containing polymerizable unsaturated monomeric unit as a constituent component. With use of said phosphoric acid group-containing non-aqueous dispersion, there can be improved interlayer adhesivity between a metallic coating film, which is formed from a leafing type aluminum flake pigment, and another coating film adjacent thereto, without reducing the excellent effects such as dense metallic feeling of the coated surface, a chrome plating-like finish, and strong brightness feeling and strong flip-flop perperties, which are produced by such a metallic coating film.
The present invention relates to compounds of the formula (I) and pharmaceutically acceptable salts and solvates thereof, wherein the substituents are defined herein, to compositions containing such compounds and to the uses of such compounds for the treatment of allergic and respiratory conditions.
Unprotected β-arylethylamines were directly accessed via 1,2-aminoarylation of alkenes under operationally simple conditions, thanks to a cooperative effect between an iron (II) catalyst and the solvent hexafluoroisopropanol. This one-pot sequential protocol did not require pre-activated (hetero)arenes and proved compatible with a broad range of drug-oriented functional groups.
