Abstract

A new mild and chemoselective protection of aldehydes as 1,3-dithiolanes using eerie ammonium nitrate as a catalyst is described. High yields are obtained at room temperature even in the presence of ketones. While alicyclic ketones may also be protected at elevated temperature, aromatic and acyclic ketones remained uneffected.
