The present invention provides compounds of formula (I) and pharmaceutically acceptable salts thereof, wherein R1 and R2 are as defined in the specification, processes for their preparation, pharmaceutical compositions containing them and their use in therapy.
reductive dicarbo-functionalization of alkenes. Two distinct readily available electrophiles, namely Csp2- and Csp3- halides are added simultaneously across a variety of olefins (vinyl amides, vinyl boranes, vinyl phosphates) at room temperature in a highly regio- and enantioselec-tive manner. The reaction, devoid of sensitive of organometallic reagents, takes advantage of an in situ generated chiral

Transition metal-catalyzed direct C–H bond functionalization enabled by transient ligands has become an attractive topic. Here we report a palladium-catalyzed site-selective arylation of β-C(sp3)–H bonds in aliphatic ketones with β-alanine as the transient ligand.

Methods that providerapidaccess to new heterocyclic structures in biologically relevant chemical space provide important opportunities in drug discovery. Here, a strategy is described for the preparation of 2,2‐disubstituted azetidines, pyrrolidines, piperidines, and azepanes bearing ester and diverse aryl substituents. A one‐pot rhodium catalyzed N–H insertion and cyclization sequence uses diazo
