Palladium-catalyzed intramolecular oxypalladation-initiated cascade: solvent-dependent chemodivergent approach to functionalized benzazepines and tetrahydroquinolines

Abstract

Palladium-catalyzed, solvent-dependent intramolecular oxypalladation-triggered domino sequences of internal alkynes bearing tethered nucleophilic carboxylic ester and electrophilic enone functionalities were developed for the chemodivergent synthesis of two completely distinct biologically significant complex molecules including isochromenone-fused benzazepines and isobenzofuranone-fused tetrahydroquinolines/chromanes in a single synthetic operation.
