Abstract

2-Alkyl- or 2,2-dialkyl-1,3-oxathiolanes can be effectively prepared from aldehydes or ketones and 2-mercaptoethanol, with triisopropylsilyl triflate as a catalyst. The reaction is over within minutes and, despite the fact that water is nor removed during the reaction, the yields of products are high.

Keywords: Ketone; Aldehyde; Protection; 1,3-Oxathiolane.
