A direct spirocyclization approach was adopted for the concise chemical synthesis of a class of spiro[cyclohexane-2-indoline] alkaloids. Stereochemically complementary spirocyclic systems could be generated by manipulation of the spirocyclization pathway to favor the kinetic or thermodynamic product.
