title: Single-flask synthesis of N-acylated indoles by catalytic dehydrogenative coupling with primary alcohols.
abstract: Indoles and alcohols can be coupled in a dehydrogenative process catalyzed by tetrapropylammonium perruthenate. This efficient approach to indolylamides proceeds in a single flask under mild conditions. By employing substituted indoles and alkyl, branched, or benzylic alcohols, a variety of indolylamides can be formed. Aryl indolylamides can be functionalized through an additional dehydrogenative coupling to furnish elaborated polycyclic heterocycles similar to biologically active structures previously reported.
