Palladium-catalyzed α-arylation of indolin-3-ones

A method for the catalytic α-arylation of indolin-3-ones was developed. The catalytic system comprising Pd(dba) 2 and PAd 3 was found to be optimal for the transformation. The protocol features broad functional group compatibility in that a range of arylated indoxyl derivatives bearing a fully subst...

Summary:A method for the catalytic α-arylation of indolin-3-ones was developed. The catalytic system comprising Pd(dba) 2 and PAd 3 was found to be optimal for the transformation. The protocol features broad functional group compatibility in that a range of arylated indoxyl derivatives bearing a fully substituted carbon center was synthesized with high efficiency. A preliminary bioassay study revealed that the selected indole-substituted indolin-3-ones exhibit favorable cytotoxic activities against HCT-116 cancer cell line. A general route to C2-(hetero)arylated indolin-3-ones bearing a fully substituted α-center was established.
