Yu, Hai-Feng published the artcileChemoselective and odorless transthioacetalization of acetals using -oxo-ketene dithioacetals as thiol equivalents, Category: dioxole, the publication is Synthetic Communications (2013), 43(9), 1280-1286, database is CAplus.
Using α-oxo-ketene dithioacetals as odorless thiol equivlents, an efficient and odorless transthioacetalization of acetals has been developed. In the presence of MeCOCl in MeOH, the cleavage of commences to generate thiols at both room and reflux temperatures, and the generated thiols then react with acetals to give correspecting thioacetals e. g., I in good yield. This transthioacetalization is characterized by mild reaction conditions, simple procedure, good yields, and perfect chemoselectivity.
