A variety of structurally novel polycyclic sulfonyl indolines have been synthesized via FeCl2-catalyzed or UV-driven intramolecular formal [2 + 2 + 1] dearomatizing cyclization reactions of N-(1H-indol-3-yl)methyl)propiolamides with NaHSO3 in an aqueous medium. The reactions involve the formation of one C-C bond and two C-S bonds in a single step.

The invention discloses a synthetic method for N-alkyl-2-aryl-indol-3-al and belongs to the technical field of chemical pharmacy and fine chemical preparation. Polysubstituted functionalized indole is an important organic compound. Metal-catalyzed sulfonyl triazole is decomposed into metal carbine, and the metal carbine produces a C-H bond insertion reaction for cyclization to obtain N-alkyl-2-aryl-indol-3-al, that is to say, a 1,2,3-trisubstituted indole structure. The method realizes effective synthesis of high-added-value cyclopropylazacyclo, provides a new technological route for preparing polysubstituted indole derivatives and can be widely applied to the field of chemical pharmacy and fine chemical engineering.

A method for convenient synthesis of N-alkyl-2-aryl-indole-3-carbaldehyde has been described. A variety of highly valuable indolyl aldehydes have been prepared through this method. Electron donating groups on both aromatic rings (anilinyl and benzyl) facilitate the formation of the desired products. A benzylic C-H insertion by rhodium carbene is the key step for this transformation. This journal is

This paper describes the direct cyanation of indoles and benzofurans employing N,N-dimethylformamide (DMF) as both reagent and solvent. Isotopic labeling experiments indicated that both the N and the C of the cyano group derived from DMF. This transformation offers an alternative method for preparing aryl nitriles, though it is currently limited in scope to indoles and benzofurans.
