typical applied unsaturated substrates include alkenes, alkynes and imines. Carbonyl is perhaps the most common unsaturated group in nature. This work demonstrates a novel CO bond formation through carbon‐centered radical addition to the carbonyloxygen of amide or ester, in which amide and ester groups are easily activated through the radical process.

examines local strategies used to build leadership roles and enlist public support in a newly literate PapuaNewGuinean highlands rural community. The ethnographic evidence presented shows how the relationship between literacy and local ideas about modernisation and development has facilitated a shift in patterns of local political structures. When literacy is viewed as an unequally distributed and

copper-catalyzed oxidativecarboamination of maleimides with alkyl amines and α-bromo carboxylates is described. These multicomponent reactions show good functional group compatibility and are suitable for the late-stage modification of a series of neuroprotective agents, providing a direct path for the library synthesis of 3-carbo-4-amino maleimides. The initial copper-catalyzed oxidative amination of
