DOIAbstract
A spiroketal bisphosphine (SKP) derived chiral digold complex is identified as a powerful catalyst for the highly diastereo- and enantioselective synthesis of spirocyclopropyloxindoles from diazooxindoles and a broad range of alkenes, including both <i>cis</i> and <i>trans</i> 1,2-disubstituted alkenes
