Compounds of formula (I): wherein R1, R2, R3, L1, L2, and Y are as defined herein, are useful for the treatment or prophylaxis of conditions such as Duchenne muscular dystrophy, Becker muscular dystrophy, and cachexia.
building blocks in pharmaceutical and materials chemistry. Synthesis of 2-amino-5-(het)arylpyridine derivatives was explored via sequential chemoselective palladium-catalyzed amination and Suzuki–Miyaura cross-coupling reaction. 5-Bromo-2-tosyloxypyridine as a starting material, a new carbon–nitrogen bond was successfully formed chemoselectively on bromide over OTs group, followed by Suzuki–Miyaura couplings
Disclosed herein are novel compounds and pharmaceutical compositions comprising these compounds. In some embodiments, the compounds are inhibitors of the tryptase enzyme and are useful for treating allergic rhinitis, asthma, vascular injury (e.g., restenosis and atherosclerosis), inflammatory bowel disease, arthritis, psoriasis, anaphylaxis, wounds, infections, and other allergy and inflammatory related diseases.

A new catalyst system capable of selective chloride functionalization in the Pd-catalyzedamination of 3,2- and 5,2- Br/Cl-pyridines is reported. A reaction optimization strategy employing ligand parametrization led to the identification of 1,1′-bis[bis(dimethylamino)phosphino]ferrocene “DMAPF”, a readily available yet previously unutilized diphosphine, as a uniquely effective ligand for this transformation
