Pd/C and RuCl2(PPh3)3/DPEphos effectively catalyzed the alkylation of indole with alcohols to give 3‐substituted indoles selectively. Various types of substrates were examined and were found to give the corresponding 3‐substituted indoles in up to 99 % yield. Under different reaction conditions, RuCl2(PPh3)3/DPEphos catalyzed the selective formation of bis(3‐indolyl)phenylmethane derivatives.

We present the coupling of primary and secondary benzylalcohols with indoles to form 3-benzylated indoles and H2O that is catalyzed, for the first time, by a complex of earth-abundant iron. This transformation accommodates a variety of substrates and is distinguished by its operational simplicity, sustainability, high functional-group tolerance, and amenability to gram-scale synthesis. On the basis

Disclosed herein are compounds capable of inducing apoptosis through promoting Nur77 interaction with Bcl-2 and through modulating mitochondrial activities. Also disclosed herein are compositions and methods using these compounds and compositions. Nur77 is a key regulator of Bcl-2 activities and is capable of converting Bcl-2 from an anti-apoptotic protein to a pro-apoptotic protein. Small molecules that directly modulate the Nur77/Bcl-2 apoptotic pathways are promising for treating diseases with abnormal levels of Bcl-2, Nur77, or combinations thereof, including cancers.

A highly efficient copper(II) catalyst system for alkylation of indoles with alcohols via hydrogen borrowing method has been developed to afford C3-alkylated indoles in good to excellent yields. Cu(OAc)2 in the combination with dppm ligand has been found to be the most suitable catalyst system for this alkylation reaction.
