Abstract
Divergent synthesis of indoles, oxindoles, isocoumarins and isoquinolinones is achieved by a general Pd-catalyzed retro-aldol reaction of β-hydroxy ketones/esters with aryl halides bearing an ortho-nitro, -ester or -nitrile group. DFT insights have been presented to rationalize the experimental observations and the chemoselectivity.
