This communication describes the development of a room-temperature ligand-directed C-H arylation reaction using aryldiazoniumsalts. This was achieved by the successful merger of palladium-catalyzed C-H functionalization and visible-lightphotoredoxcatalysis. The new method is general for a variety of directing groups and tolerates many common functional groups.

The present invention relates to compounds useful as inhibitors of phosphatidylinositol-3-phosphate 5-kinase (PIKfyve) as well as their use for treating diseases and disorders associated with PIKfyve.
The arylation of pyrazole and derivatives can be achieved by coupling arenediazonium species (formed in situ fromanilines) by using a catalytic system that employs low‐toxicity and inexpensive copper metal under very mild and ligand‐free conditions (T=20 °C). From other nitrogenheterocycles, the presence of an additive (NBu4I) significantly improves the efficiency of the catalytic system. These results

The present invention provides novel spiro[cyclobutane-1,3'-indolin]-2'- derivatives of formula (I) in which Cy, R1, R2, L and 'm' are have the meaning given in the specification, and pharmaceutically acceptable salts thereof. The compounds of formula (I) are useful as bromodomain inhibitors in the treatment or prevention of diseases or disorders where bromodomain inhibition is desired.
A facile and convenient strategy for the assembly of N-arylated heterocycles has been demonstrated using a MnCl2.4H2O/trans-1,2-diaminocyclohexane catalyst and K3PO4 as the base in water.
