Author: Fan, Mengyang and Ma, Dawei
Subjects: *AMINO acid derivatives, *PALLADIUM catalysts, *CARBON-hydrogen bonds, *ARYL iodides, *CHEMICAL yield
Abstract: Die gut verfügbare Hilfsgruppe 2 ‐ Methoxyiminoacetyl erleichtert palladiumkatalysierte γ ‐ Arylierungen an C(sp3) ‐ H ‐ Bindungen. Das Auxiliar kann durch Behandlung mit 1 n KOH bei Raumtemperatur leicht entfernt werden; alternativ lässt es sich für Peptidsynthesen in eine Glycineinheit umwandeln. [ABSTRACT FROM AUTHOR]

Abstract: Intramolecular dehydrogenative cyclizationof 2-methoxyiminoacyl-protectedphenylalanine derivatives proceeded at 110 °C under catalysisof Pd(OAc)2in the presence of 1-fluoro-2,4,6-trimethylpyridiniumtetrafluoroborate to afford substituted indoline-2-carboxylates thatwere converted into indoline-2-carboxylate-embodied dipeptides viaRaney Ni-catalyzed hydrogenation.
