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 cis and trans 1,2-disubstituted alkenes.

It is reported for the first time that Hg(II) can catalyze the cyclopropanation of diazo reagents and alkenes, which contributes to the unprecedented highly diastereo- and enantioselective synthesis of spirocyclopropyloxindoles.

The first catalytic asymmetric cyclopropanation using styrene and diazooxindole was achieved with Rh2(S-PTTL)4. The reaction proceeded smoothly with 1 mol% catalyst loading to provide a good yield of the biologically important spiro-cyclopropyloxindole product with moderate to good enantioselectivity and excellent diastereoselectivity.
