Dehydrogenative annulation under oxidizing reagent-free conditions is an ideal strategy to construct cyclic structures. Reported herein is an unprecedented synthesis of pyrrolidine and tetrahydropyridine derivatives through electrochemical dehydrogenative annulation of N-allyl amides with 1,3-dicarbonyl compounds. The electrolytic method employs an organic redox catalyst, which obviates the need for oxidizing reagents and transition-metal catalysts. In these reactions, the N-allyl amides serve as a four-atom donor to react with dimethyl malonate to give pyrrolidines by a (4+1) annulation, or with β-ketoesters to afford tetrahydropyridine derivatives by a (4+2) annulation.

A palladium-catalyzed oxidative arylalkylation of unactivated alkenes involving dual C-H bond cleavage of arene and acetonitrile was developed. This reaction was promoted by pyridine as a ligand, and the ratio of palladium to pyridine is vital for this transformation. A series of nitrile-containing indolines were efficiently provided in moderate to good yields. Copyright

Prochiral allylic amines are reduced as their chlorhydrates using rhodium complexes of various 1,2-, 1,3- and 1,4-diphosphinocompounds with enantiomeric excess (e.e.) up to 60percent.The N-acetyl derivatives of the allylic amines are reduced with low e.e.
