Demonstrates the synthesis of spirocyclohexadienones in various yields, suggesting a new synthetic approach.
-transfer and tautomerization as the key catalytic process and enable facile access to various spirocyclohexadienone-fused 2-sulfonamidoindolines, giving the spirocyclic products in moderate to excellent yields with good to excellent enantioselectivities. These procedures may provide alternative synthetic strategy for the enrichment of spirooxindoles.
