Montmorillonite K-10 clay has been found to be a mild and efficient solidcatalyst for the protection of a variety of carbonylcompounds, such as oxathiolanes, with 2-mercaptoethanol in good to excellent yields. In addition, by using this catalyst, high chemoselective protection of aldehydes in presence of ketones has been achieved.
