Thiophene derivatives of formula (I) and a pharmaceutically acceptable salt thereof are provided. These compounds have utility for the treatment or prevention of disorders caused by IgE, such as allergy, type 1 hypersensitivity or familiar sinus inflammation.
Homoleptic lanthanide complex Y[N(TMS)2]3 is an efficient homogeneous catalyst for the hydroboration reduction of secondary amides and tertiary amides to corresponding amines. A series of amides containing different functional groups such as cyano, nitro, and vinyl groups were found to be well-tolerated. This transformation has also been nicely applied to the synthesis of indoles and piribedil. Detailed
Efficient and recyclable ruthenium catalysts were synthesized from readily available polystyrene‐ or silica‐supported phosphine ligands. Catalysts bound to the polymer support through an ether linkage showed good to excellent activity towards the N‐alkylation of primary and secondary amines to afford the alkylated products in 62–99 % yield at 120–140 °C. The supported phosphine ligand/ruthenium ratio

The catalytic intermoleculardiamination of unactivated alkenes with electron-rich amino sources is a challenge. Herein, by employing a directing-group strategy, a copper-catalyzeddiamination of unactivated alkenes was realized. Symmetrical diamines were efficiently produced in a highly diastereoselective manner with readily available dialkylamines as amino sources, while a one-pot and two-step operation
The present invention provides novel compounds that are antagonists of PI3 kinase, PI3 kinase and tryosine kinase, PI3Kinase and mTOR, or PI3Kinase, mTOR and tryosine kinase.
