Sonstige Hinweise

Acidic amides are superior directing groups for promoting C-H activation reactions with both Pd(0)/PR3 and Pd(II) catalysts.

Used in the Preparation of
  • Lactams via palladium-catalyzed olefination of arylamides with benzylacrylate, followed by 1,4-conjugate addition
  • N-(fluorinated aryl)benzamides as substrates for regioselective C-H amination reactions with O-benzoylhydroxylamines
  • Substituted succinimides via palladium-catalyzed carbonylation of N-aryl amides
  • N-aryl cyclopropanecarboxamide substrates and various amino acid ligands for palladium-catalyzed C-H activation of cyclopropanes

C-H amination of N-aryl benzamides with O-benzoyl hydroxylamines has been achieved with either Pd(II) or Pd(0) catalysts. Furthermore, we demonstrate that secondary amines can be directly used with benzoyl peroxide in a one-pot procedure that proceeds via the in situ

Pd(II)-catalyzed β-C(sp(3))-H carbonylation of N-arylamides under CO (1 atm) has been achieved. Following amide-directed C(sp(3))-H cleavage and insertion of CO into the resulting [Pd(II)-C(sp(3))] bond, intramolecular C-N reductive elimination gave the corresponding succinimides, which could be readily converted to 1,4-dicarbonyl

Systematic ligand development has led to the identification of novel mono-N-protected amino acid ligands for Pd(II)-catalyzed enantioselective C-H activation of cyclopropanes. A diverse range of organoboron reagents can be used as coupling partners, and the reaction proceeds under mild conditions.

Yu Group – Professor Product Portal

The Yu program centers around the discovery of catalytic carbon–carbon and carbon–heteroatom bond forming reactions based on C–H activation. Target transformations are selected to enable 1) the use of simple and abundant starting materials such as aliphatic acids, amines and alcohols, and 2) disconnections that drastically shorten the synthesis of a drug molecule or a major class of biologically active compounds.
