Catalytic kinetic resolution of cyclic secondary amines
The catalytic resolution of racemic cyclic amines has been achieved by an enantioselective amidation reaction featuring an achiral N-heterocyclic carbene catalyst and a new chiral hydroxamic acid cocatalyst working in concert. The reactions proceed at room temperature, do not generate nonvolatile byproducts, and provide enantioenriched amines by aqueous extraction.

Electrochemical deallylation of α-allyl cyclic amines and synthesis of optically active quaternary cyclic amino acids
Electrochemical oxidation of α-allylated and α-betizylated N-acylated cyclic amines by using a graphite anode easily affords the corresponding α-methoxylated products with up to 76% yield. Ease of oxidation was affected by the type of electrode, the size
