A vanadium-catalyzed method for the oxidative kinetic resolution of alpha-hydroxyesters, using oxygen as the terminal oxidant, is described. The catalyst is generated in situ from vanadium(V) tri-iso-propoxyoxide in combination with a tridentate ligand derived from 3,5-di-tert-butylsalicylaldehyde and (S)-tert-leucinol. The reaction allows for the enantioselectivesynthesis of both aromatic and aliphatic

The enantioselective total synthesis of the 3,4-fused indole alkaloid ht-13-A has been achieved. The synthesis features a zinc-mediated propargylation, a rhodium-catalyzed intramolecular C-H activationreaction, and a methylamine-mediated cyclization. The...
