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

NaOtBu — an alkoxide salt — enables simple access to low-oxidation-state catalysis using sustainable first-row transition metals (Fe, Co, Mn, Ni). The approach works across a widerange of reductive alkene and alkyne functionlization reactions including hydroboration, hydrosilylation, hydrogenation, hydrovinylation and [2π+2π] cyclization reactions.

A facile acid-catalyzed acylation of indoles with 1,3-dione as an eco-friendly acylating agent was developed. This protocol combines C-C bond cleavage and heterocyclic C-H bond functionalization to form new C-C bonds. Based on the detailed mechanistic studies, a credible mechanistic pathway was proposed.
