Montmorillonite K-10 clay has been found to be a mild and efficient solid catalyst for the protection of a variety of carbonyl compounds, 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.

An efficient method for the preparation of 1,3-oxathiolanes from aldehydes and ketones with 2-mercaptoethanol in the presence of a catalytic amount of indium trifluoromethanesulfonate is reported.
Zirconium tetrachloride (ZrCl4) as an efficient and chemoselective catalyst for conversion of carbonyl compounds to 1,3-oxathiolanes
Karimi, Babak,Seradj, Hassan
, p. 805 - 806 (2007/10/03)
Different types of aldehydes and ketones can be efficiently converted into their corresponding 1,3-oxathiolanes using 2-mercaptoethanol (1.5-3.2 equiv.) in the presence of catalytic amount (0.04-0.15 equiv.) of ZrCl4 in CH2Cl2/
Interconversion of oxathiolanes and carbonyls under essentially identical conditions
Ravindranathan,Chavan, Subhash P.,Dantale, Shubhada W.
, p. 2285 - 2288 (2007/10/02)
A catalytic, non-aqueous protocol for the interconversion of oxathiolanes and carbonyl compounds at room temperature is described.
Comparative radioprotective activity of various pentagonal compounds with two heteroatomes
Robbe,Fernandez,Dubief,et al.
, p. 235 - 243 (2007/10/02)
Various heterocyclic compounds with two heteroatomes were synthesized and their potential radioprotective activity was tested. This study shows the interest of phenylthiazolidines derivatives in chemical radioprotection.
