5-Membered N-heterocyclic compounds by dimethyl carbonate chemistry
Aliphatic and aromatic 1,4-bifunctional compounds bearing a primary alcoholic function and an amine can be efficiently cyclised with dimethyl carbonates in the presence of a base to achieve 5-membered N-heterocyclic compounds. This novel synthetic pathway

Palladium-catalyzed sp3 C-H activation of simple alkyl groups: Direct preparation of indoline derivatives from N-alkyl-2-bromoanilines
The sp3 C-H activation of a simple alkyl group catalyzed by palladium(O) provides a novel and convenient strategy for the synthesis of various indolines from simple precursors, such as N-alkyl-2-bromoanilines. This study demonstrates that assisting moieties In the substrate such as a pyridine or quaternary carbon are not always necessary for sp3 C-H activation.
