Rh(III)catalyzed general strategy was developed for the site selective remote C4 (sp2) and C2 (sp3)-methyl thiolation of indole core keeping the oxime directing group at the C3 position. The transformation was accomplished undermildconditions with wide scope and functional group tolerance. The directing group can easily be removed after operation. Methyl substitution at the C2 position of indole core

way to synthesize with high selectivity a variety of functionalized indoles with potent biological properties has been developed. Notably, 2,4-dialkynyl indole products were obtained by direct double C−H bond alkynylation, whereas alkynyl at the C4 position could convert to carbonyl to generate 2-alkynyl-3,4-diacetyl indoles fast and effectively. Additionally, a one-pot relay catalytic reaction led to
