A strategy involving palladium-catalysed aromatic C-H functionalisation/intramolecular alkenylation provides a convenient and direct synthesis of 3-alkylideneoxindoles. In the presence of 5 mol% of PdCl(2)MeCN(2) and AgOCOCF(3), a wide variety of N-cinnamoylanilines gave 3-alkylideneoxindoles in moderate to good yield.

A methodology to access chiral 3,3′-spiro-phosphonylpyrazoline oxindoles via an asymmetric 1,3-dipolarcycloadditionreaction of substituted methyleneindolinones with α-diazomethylphosphonate in the catalysis of tertiary amine thiourea and 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) has been established. This method exhibits high functional group compatibility, where a wide range of methyleneindolinones
