%X A PPh3 mediated reductive annulation reaction between
isatins and 4,4-dicyano-2-methylenebut-3-enoates was developed. The
reaction provided an alternative method for constructing five- and
three-membered all-carbon spirooxindole compounds. Lithium chloride
as a Lewis acid played a key role in the synthesis of spirocyclopentenyl
oxindole compounds.
