Spirocyclic oxindoles undergo an enantioselective oxygenation reaction (nine examples; e.r. up to 97:3) upon catalysis by a chiral ruthenium porphyrin complex (1 mol%). The catalyst exhibits a lactam ring, which is responsible for substrate association through hydrogen bonds, and an active ruthenium center, which is in a defined spatial relationship to the oxygenation substrate. DFT calculations illustrate the perfect alignment of the active site with the reactive C-H bond and suggest-in line with the kinetic isotope effect-an oxygen rebound mechanism for the reaction.
Synthesis of A2B6-type [36]octaphyrins: Copper(II)-metalation-induced fragmentation reactions to porphyrins and N-fusion reactions of meso-(3-thienyl) substituents
