The first preparation of the N,C-coupled naphthylisoquinolinealkaloid ancistrocladinium A and its likewise naturally occurring minor atropisomer, in an atropisomerically pure form, is described. The synthesis succeeded by resolution of the already rotationally hindered, and thus atropo-diastereomeric acetamide precursors, which were then, without major loss of stereochemical information, cyclized
Asymmetric Transfer Hydrogenative Amination of Benzylic Ketones Catalyzed by Cp*Ir(III) Complexes Bearing a Chiral <i>N</i>-(2-Picolyl)sulfonamidato Ligand
A convenient asymmetric reductive amination of benzylic ketones (α-arylated ketones) catalyzed by newly designed Cp*Ir complexes bearing a chiral N-(2-picolyl)sulfonamidato ligand was developed. Using readily available β-aminoalcohols as chiral aminating agents, a range of benzo-fused and acyclic ketones were successfully reduced with formic acid in methanol at 40 °C to afford amines with favorable
