A simple and efficient thiol-mediated addition of ketones to aromatic and aliphatic aldehydes is reported. This thermodynamically controlled Pummerer/aldolreaction, which can tolerate both moisture and protic functional groups, provides a direct entry to syn-β-thioketones in high chemo- and regioselectivity. Mechanistic studies revealed that selective transformation of the aldehyde to an electrophilic

Zirconium chloride efficiently catalyzes the one-pot, three-component reaction of an aryl aldehyde, cyclic or acyclic enolizable ketones, and thiols under solvent-free conditions at room temperature to afford the corresponding beta-aryl-beta-mercaptoketones via aldol-Michael addition reactions. This methodology affords a large number of beta-aryl-beta-mercapto ketone derivatives in high yields and in short reaction times. (c) 2007 Elsevier Ltd. All rights reserved.
