Asymmetric transfer hydrogenation of seven membered tricyclic ketones: N-substituted dibenzo[b,e]azepine-6,11-dione driven by nonclassical CH/O interactions

Abstract

Enantioselective transfer hydrogenation of dibenzo-fused-azepine-diones: <italic>N</italic>-substituted dibenzo[<italic>b</italic>,<italic>e</italic>]azepin-6-11-dione was achieved by ruthenium catalysis in the presence of formic acid/triethylamine as a mild hydrogen source.
