The selective oxidation of C2-alkyl-substituted indoles to 3-oxindole and the selective C-H oxygenation or amination of C2,C3-dialkyl-substituted indoles at C2 are reported under mild conditions. The position of the alkyl substitution on the indole directs the reaction to different pathways under similar conditions.
Tandem Wittig – Reductive annulation decarboxylation approach for the synthesis of indole and 2-substituted indoles
Volvoikar, Prajesh S.,Tilve
supporting information, p. 1851 - 1854 (2018/04/14)
A simple tandem Wittig reaction-reductive decarboxylation route is established for the synthesis of indoles from commercially available o-nitrobenzaldehydes and a stable phosphorane. The method allows access to indoles in a very fast manner without involving any metal or expensive reagents or inert atmosphere. Also 2-substituted indoles are obtained which forms an important core of many biological active compounds.

Protecting-group-free transformation is a challenging and important issue in atom-economical organic synthesis. The η6-arene/N-Me-sulfonyldiamine-Ru(II)-BF4 complex-catalyzed asymmetric hydrogenation of 2-substituted unprotected indoles in weakly acidic hexafluoroisopropanol gives optically active indoline compounds with up to >99% ee. Under mild reaction media, halogen atoms and synthetically important protecting groups (e.g., silyl ether, acetal, benzyl ether, and ester) on indoles are maintained, which is advantageous for the synthesis of further complex indoline molecules.
A N-heterocyclic carbene (NHC) platinum complex as pre-catalyst for the intramolecular hydroamination of olefins with secondary alkylamines and oxidative amination of ω-alkenic amines
Zhang, Rui,Xu, Qin,Mei, Liang-Yong,Li, Sheng-Ke,Shi, Min
supporting information; experimental part, p. 3172 - 3178 (2012/06/01)
A N-heterocyclic carbene (NHC) platinum complex 3 prepared from BINAM was found to be a highly effective pre-catalyst for the intramolecular hydroamination of olefins with secondary alkylamines to give the corresponding intramolecular hydroamination products in excellent yields. The substrate scope has been carefully examined and the plausible reaction mechanism has been also proposed.

Novel benzofuran-3-one indole inhibitors of PI3 kinase-α and the mammalian target of rapamycin: Hit to lead studies
Bursavich, Matthew G.,Brooijmans, Natasja,Feldberg, Lawrence,Hollander, Irwin,Kim, Stephen,Lombardi, Sabrina,Park, Kaapjoo,Mallon, Robert,Gilbert, Adam M.
scheme or table, p. 2586 - 2590 (2010/06/19)
A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110α (PI3K-α), good pharmaceutical properties, selectivity versus p110γ (PI3K-γ), and tunable selectivity versus the mammalian target of rapamycin (mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-α and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells.

Nonreductive Desulfenylation of 3-Indolyl Sulfides. Improved Syntheses of 2-Substituted Indoles and 2-Indolyl Sulfides
Hamel, Pierre,Zajac, Nicolas,Atkinson, Joseph G.,Girard, Yves
, p. 6372 - 6377 (2007/10/02)
Desulfenylation of 3-indolyl sulfides to the corresponding 3-unsubstituted indoles is usually carried out under reductive conditions, thus accommodating only substituents which are resistant to reduction.We have developed a nonreductive procedure for removal of a sulfide at the 3-position of indoles, using trifluoroacetic acid in the presence of a thiol as trapping agent, which is compatible with a large array of functionalities on the indole ring.In addition, the desulfenylation occurs selectively at the 3-position of the indole, and sulfide groups at other positions of the molecule remain untouched.Thus, indole 2,3-bis-sulfides are selectively desulfenylated at the 3-position, affording 3-unsubstituted 2-indolyl sulfides.This methodology broadens the use of sulfide as a protecting group for the 3-position of indoles.
