The Chan–Evans–Lam reaction is a valuable C–N bond forming process. However, aryl boronic acidpinacol (BPin) ester reagents can be difficult coupling partners that often deliver low yields, in particular in reactions with aryl amines. Herein, we report effective reaction conditions for the Chan–Evans–Lam amination of aryl BPin with alkyl and aryl amines. A mixed MeCN/EtOH solvent system was found

iridium catalyst for ortho‐selectiveC−Hborylation of challenging secondary aromatic amide substrates, and the regioselectivity is controlled by hydrogen‐bond interactions. The BAIPy‐Ir catalyst forms three hydrogen bonds with the substrate during the crucial activation step, and allows ortho‐C−Hborylation with high selectivity. The catalyst displays unprecedented orthoselectivities for a wide variety

This invention relates to compounds of formula (I) and methods of treatment using the compounds. The compounds of the invention can be used in combination with antibacterial agents to treat bacterial infections. More specifically, the compounds of formula (I) can be used in combination with a class of antibacterial agents known as carbapenems. The novel compounds of the present invention are enzyme inhibitors and more particularly are metallo-β-lactamase inhibitors. (I)
A new concept for the meta‐selective borylation of aromatic amides is described. It has been demonstrated that while esters gave para borylations, amides lead to meta borylations. For achieving high meta selectivity, an L‐shaped bifunctional ligand has been employed and engages in an O⋅⋅⋅K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction
