Abstractmagnified imageAn efficient and chemoselective palladium‐catalyzed direct B‐alkyl Suzuki–Miyaura cross‐coupling of trialkylboranes with diversely functionalized aryl bromides is described. A wide variety of unmasked acidic or basic functions are tolerated. The mild non‐aqueous conditions are compatible with aldehydes, ketones, nitriles, chloro substitution as well as base‐labile phenolic Piv and TBS protecting groups. The anhydrous conditions were found to be advantageous for aryl bromide substrates. A potent CEPT inhibitor was efficiently synthesised using this protocol.

A highly efficient regio- and enantioselective monohydrogenation of 1,4-dienes has been realized using an iridium catalyst with a chiral N,P-ligand under mild conditions. The substrate scope was studied and included both unfunctionalized as well as functionalized substituents on the meta- or para-position. Substrates having substituents with functionalities such as silyl protected alcohols or ketals
