Synthesis of Indole/Benzofuran-Containing Diarylmethanes through Palladium-Catalyzed Reaction of Indolylmethyl or Benzofuranylmethyl Acetates with Boronic Acids
The palladium-catalyzed synthesis of indole/benzofuran-containing diarylmethanes starting from indolylmethyl or benzofuranylmethyl acetates with boronic acids has been investigated. The success of the reaction is influenced by the choice of precatalyst: with indolylmethyl acetates the reaction works well with [Pd(η3-C3H5)Cl]2/XPhos while with benzofuranylmethyl acetates Pd2(dba)3/XPhos is more efficient

Transfers: Triethylsilane and potassium tert-butoxide react to form a highly attractive and versatile system. The work herein highlights the reductive transformations which lead to 1) C−N bond cleavage in N-benzyl and N-allylindoles and 2) reduction of polycyclic arenes to their dihydro derivatives.
The developments of hydrogensources stand at the forefront of asymmetric reduction. In contrast to the well-studied alcohols as hydrogensources via β-hydride elimination, the direct utilization of the proton of alcohols as a hydrogensource for activator-mediated asymmetric reduction is rarely explored. Herein we report the proton of alcohols as a hydrogensource in diboron-mediated palladium-catalyzed
