Supported-Pd catalyzed carbonylative synthesis of phthalimides and isoindolinones using Oxalic acid as in situ CO surrogate with 2-iodobenzamides and 2-iodobenzylanilines in ppm-level catalyst loading
Selective Synthesis of Either Isoindole- or Isoindoline-1-carboxylic Acid Esters by Pd(0)-Catalyzed Enolate Arylation
摘要:
Two efficient palladium-catalyzed intramolecular alpha-arylation reactions of alpha-amino acid esters have been developed that allow either 1-isoindolecarboxylic acid esters or the corresponding isoindolines to be selectively synthesized simply by a slight change of reaction conditions.
A new strategy for the synthesis of tetrahydroisoquinolines based on the Pd0‐catalyzed intramolecular α‐arylation of sulfones is reported. The combination of this Pd‐catalyzed reaction with intermolecular Michael and aza‐Michael reactions allows the development of two‐ and three‐step domino processes to synthesize diversely functionalized scaffolds from readily available starting materials.
