palladium-mediated cascade Tsuji–Trost reaction/Heck coupling of N-Ts o-bromoanilines with 4-acetoxy-2-butenonic acidderivatives using a Pd(OAc)2/P(o-tol)3/DIPEA system is described for a straightforward synthesis of indole-3-acetic acidderivatives. This methodology was successfully applied to synthesize various substituted indole/azaindole-3-acetic acidderivatives and Almotriptan, which is a drug for the acute
