Gold(I)-catalyzed formation of dihydroquinolines and indoles from N-aminophenyl propargyl malonates

The use of [XPhosAu(NCMe)]SbF(6) in nitromethane at 100 degrees C allows the rapid and efficient formation of variously substituted dihydroquinolines, which can be subsequently converted into indoles by a rare photochemical rearrangement.
