construction of 3,3-disubstituted indol-2-ones from isatylidenes by utilizing amphiphilic bis-π-allylpalladium and related intermediates. The developed strategy is a new method for the quaternization of position 3 of the indol-2-one towards disubstituted functionalized indol-2-ones. These products were subjected to ring-closing metathesis towards the synthesis of spiro[cyclohexene-1,3′-indol]-2′-ones
