Graphical Abstract

Abstract

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.
