Rh-catalyzed selective C-H functionalization of indoles with two routes was developed: an alkenylation-annulation with the addition of KHSO4 and alkenylation-elimination in the presence of CsOAc to the corresponding products, respectively. Notably, one-pot hydrolysis and benzoylation of the annulation products successfully afforded easily separable β-(1H-indol-2-yl)-β-amino acid derivatives.
