The Buchwald N-arylation of amines and amides is achieved efficiently in PEG (400 Daltons) as solvent medium. The solvent and catalyst recyclability is studied. Interestingly amides underwent N-arylation with better yields. Georg Thieme Verlag Stuttgart.

Herein, we have developed a rhodium-catalyzed C-H functionalization and subsequent intramolecular ring-opening/cyclization of vinylene carbonate with 2-pyrrolyl/indolylanilines, which leads to oxazolidinones in moderate to good yields. In this transformation, vinylene carbonate only eliminates one oxygen atom rather than -CO3 or CO2. Furthermore, some control experiments are conducted to elucidate the reaction mechanism.

Palladium-catalyzed sequential acylation/annulation of indoles with acyl chlorides using primary amine as the directing group

An attractive and convenient strategy for the direct acylation/annulation of indoles has been developed using Pd(0) as an efficient catalyst. The main feature of this protocol is the use of acyl chlorides as the acylating agents with the primary amine as the directing group. A variety of indolo[1,2-a]quinoxalines were readily obtained in reasonable efficiency and satisfactory yields with good functional group tolerance. Based on control experiments, a tentative catalytic mechanism was proposed.
