A wide variety of carbonyl compounds 1 can be easily protected selectively as the corresponding 1,3-oxathiolanes 2 in good yields using a catalytic amount (0.01-0.1 equiv.) of n-tetrabutylammonium tribromide in dry CH2Cl2 at 0-5°C. O
Montmorillonite K-10 clay as an efficient solid catalyst for chemoselective protection of carbonyl compounds as oxathiolanes with 2-mercaptoethanol
Gogoi, Siddhartha,Borah, Jagat C.,Barua, Nabin C.
, p. 1592 - 1594 (2004)
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.
