文摘A highly efficient and direct approach was developed to construct the structurally diverse spirooxindole skeleton,which is an important basic motif in natural products.Both the 3,30-pyrrolidonyl spirooxindoles and spiroindolin-2-one dlactones were 2smoothly obtained by the intramolecular Dieckmann cyclization of oxindoles in excellent yield under mild conditions.
