The azomethine ylide route to amine C-H functionalization: redox-versions of classic reactions and a pathway to new transformations. [PDF]
Acc Chem Res, 2015 Conspectus Redox-neutral methods for the functionalization of amine α-C–H bonds are inherently efficient because they avoid external oxidants and reductants and often do not generate unwanted byproducts. However, most of the current methods for amine α-C–
