Extending Pummerer reaction chemistry. Asymmetric synthesis of spirocyclic oxindoles via chiral indole-2-sulfoxides

The conversion of (S8)-3-(ω-allylsilane and silyl enol ether)indole-2-sulfoxides to spirocyclic indolenines and then to oxindoles proceeds, in favorable cases, with moderate levels of chirality transfer from sulfur to C(3) of the indole core. A
