One-pot Synthesis of Tetralin Derivatives from 3-Benzoylpropionic Acids: Indium-catalyzed Hydrosilylation of Ketones and Carboxylic Acids and Intramolecular Cyclization
This reducing system was composed of a small amount (1 mol %) of In(OAc)(3), Me2PhSiH, and I-2 that effectively catalyzed the hydrosilylation of two different carbonyl groups, a ketone and a carboxylic acid found in 3-benzoylpropionic acids, followed by a subsequent intramolecular cyclization that led to the one-pot preparation of tetralin derivatives.
