Indoles are an important structural motif that is commonly found in biologically active molecules. In this work, conditions for divergent couplings between imidamides and acceptor-acceptor diazo compounds were developed that afforded NH indoles and 3H ...

AbstractTreatment of indole, 2‐phenylindole, 2‐methylindole, and ethyl indole‐2‐carboxylate with thiocyanogen in acetic acid at 0° afforded the corresponding 3‐thiocyanatoindoles in quantitative yields, whereas similar treatment of 3‐methyl‐2‐phenylindoles and 2,3‐diphenylindoles gave the corresponding 6‐thiocyanatoindoles in high yields.

A new and efficient copper-catalyzed C3 aryl- and heteroarylselenation of indoles employing selenium powder has been developed. The advantages of this chemistry involve the use of cheap selenating reagents, tolerance of a variety of functional groups ...

A new ruthenium-catalyzed, heteroatom-directed strategy for C-H allylation of indoles is described. The use of allyl alcohols as coupling partners as well as pyridine as the removable directing group is highlighted. This methodology provides access to C2-

Summary Indole or indoleglycerol phosphate were incubated with crude or dialyzed enzyme extracts (pH 5.4-8.0) of pea seedlings. Neither with nor without addition of serine-like cosubstrates, any formation of auxin or an auxin precursor could be detected by means of the Avena curvature test or thin-layer chromatography.

Journal of the American Chemical Society, 2015
A highly enantioselective intramolecular arylative dearomatization of indoles via palladium-catalyzed reductive Heck reactions was developed. The new strategy led to a series of optically active indolines bearing C2-quaternary stereocenters in modest to ...
