Carbonyl compounds have been successfully converted into their corresponding oxathiolane, dithiolane, and dithiane derivatives with 2-mercaptoethanol, 1,2-ethanedithiol, and 1,3-propanedithiol using catalytic amount of yttrium triflate. In addition, by using this catalyst, high chemoselective protection of carbonyl compounds has been achieved. (C) 2004 Elsevier Ltd. All rights reserved.
