In synthetic chemistry, the protection of aldehydes and ketones is crucial during multistep synthesis of complex molecules. Organic chemists have paid substantial attention to the synthesis of 1,3-oxathiolanes and 1,3-oxathianes because of their considera

An efficient visible light photoredox catalyzed aerobic deprotection of 1,3-oxathiolanes using organic dye Eosin Y as a photocatalyst is disclosed. The deprotection procedure features the use of a metal-free catalyst, mild conditions, a broad range of substrate scope, and good functional group tolerance. 35 examples were tested under the standard conditions and most of them afforded the deprotected products in modest to high yields.

A simple and efficient method for the conversion of carbonyl compounds to oxathioacetals and dithioacetals using SA/SiO2 as an acid catalyst has been achieved. SA/SiO2 is easily recovered from the reaction mixture and can be reused at least 15 times without loss of catalytic activity.

, p. 2635 - 2637 (2007/10/03)
Montmorillonite K10 has been used in the deprotection of different aromatic and aliphatic 1,3-oxathiolanes to the corresponding carbonyl compounds in 73 to 97% yields under mild and environmentally compatible conditions.
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/
