General description

The ChemBeads product of the QPhos ligand combined with the Buchwald third Generation Palladacycle. Loaded at 5% wt. on glass beads for use in high-throughput expermentation (HTE). QPhos Pd G3 has been used in:

  • The synthesis of complex druglike moleucle via Negisihi couplings using a high-throughput experimentation approach.[1]
  • The regioselective arylboration of isoprene using cooperative Pd/Cu catalysis.[2]
  • The total synthesis of Phainanoid A and its synthetic analogues.[3][4]

Application

ChemBeads are chemical coated glass beads. ChemBeads offer improved flowability and chemical uniformity perfect for automated solid dispensing and high-throughput experimentation. The method of creating ChemBeads uses no other chemicals or surfactants allowing the user to accurately dispense sub-milligram amounts of chemical.

For general uses, product is also available in powdered form 903027

The reactivity of a representative set of 17 organozinc pivalates with 18 polyfunctional druglike electrophiles (informers) in Negishi cross-coupling reactions was evaluated by high-throughput experimentation protocols. The high-fidelity scaleup of successful reactions in parallel enabled the isolation of sufficient material
