Visible-light-promoted radical (phenylsulfonyl)methylation reactions of electron-rich heteroarenes and N-arylacrylamides have been developed starting from bromomethyl phenyl sulfone derivatives. This method provides a mild and efficient access to various (phenylsulfonyl)methylated compounds.

frequently used chemical reaction in the pharmaceutical field. Developing protocols for the nucleophilic substitution of (indol-2-yl)methyl electrophiles is important for functionalizing indoles. There are few studies on the nucleophilic substitution at the 2′-position of the electrophiles without an electron-withdrawing group at the 1-position or substituents at the 2′- and 3-positions, where the existing

A new class of C-2-symmetric bis-indole derivatives with 2,2'-linkage has been synthesized from bis-propargyl sulfones. The method involves treatment of the sulfones with catalytic amount of triethylamine to form the indole derivatives presumably via the intramolecular Michael addition to the intermediate bis-allenic sulfones. Interestingly, the expected Garratt-Braverman pathway was not followed. (C) 2009 Elsevier Ltd. All rights reserved.
