title: Synthesis of isoxazoline-functionalized phenanthridines via iminoxyl radical-participated cascade sequence.
abstract: Readily accessible β,γ-unsaturated ketoximes reacted with 2-arylphenylisonitriles under the conditions of t-BuOOH and n-Bu4NI to give isoxazoline functionalized phenanthridines via tandem intramolecular/intermolecular C-O/C-C/C-C bond formation. The reaction involves the initial generation of iminoxyl radicals from the oxidation of β,γ-unsaturated ketoximes by t-BuOOH and n-Bu4NI followed a cascade radical cyclization/addition/cyclization sequence.
