Hegedus indole synthesis

Hegedus indole synthesis
Named after	Louis S. Hegedus
Reaction type	Ring forming reaction

The Hegedus indole synthesis is a name reaction in organic chemistry that allows for the generation of indoles through palladium(II)-mediated oxidative cyclization of ortho-alkenyl anilines.^[1]^[2]^[3]^[4]^[5]^[6] The reaction can still take place for tosyl-protected amines.^[4]

Application

2-Allylaniline can be converted to 2-Methylindole using the Hegedus indole synthesis.^[1]
