The synthesis of functionalized oxindoles and benzofuranones via oxidation of 2-BMIDA indoles and benzofurans, respectively, is described. Interconversion of boron species (BMIDA→BF3K) was necessary to enable oxidation and overcome boronic acid stability issues associated with a difficult BMIDA hydrolysis. Overall, a robust process was developed that allowed access to a small library of oxindole and benzofuranone products and facilitated the step-efficient synthesis of biologically active compounds containing the oxindole pharmaco-phore.
Synthesis of Oxindoles through the gold-catalyzed oxidation of N-arylynamides

α-Oxo gold carbenoids generated by the oxidation of N-arylynamides can be trapped intramolecularly at the ortho position of the aryl ring to give functionalized oxindoles under mild reaction conditions. Pyridine N-oxide works as the oxidant, ligand, and base in this transformation. Copyright
