A hindered β-amino amide transient directing group effects di-trans-arylation of cyclohexanecarbaldehydes. The amide N-substituents are shown to affect yield and can enhance the rate of arylation compared with the α-amino acid. Addition of a pyrido

Palladium catalysed β-C(sp3)–H activation of tertiary aldehydes using a transient imine directing group enables intramolecular arylation to form substituted indane-aldehydes. A simple amine bearing a methyl ether (2-methoxyethan-1-amine) is the op

Aryl thiols can be selectively converted to sulfonimidates or sulfonamides with three new S-X connections being made selectively in one pot. Using hypervalent iodine reagents in the presence of ammonium carbamate, NH- and O-groups are transferred und

C–H Functionalisation promises a paradigm shift in synthetic planning. However, the additional steps often required to install and remove directing groups currently detracts from the efficiency. The strategy of reversible installation of a directin

Direct synthesis of NH-sulfoximines from sulfides has been achieved through O and NH transfer in the same reaction, occurring with complete selectivity. The reaction is mediated by bisacetoxyiodobenzene under simple conditions and employs inexpensive

A regioselective C—H functionalization of 2-phenylpyridines (I) is developed using a range of tertiary halides (II) and (IV) to afford challenging quaternary carbon centers.
