A new, mild and chemoselectiveprotection of aldehydes as 1,3-dithiolanes using ceric 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.
