• Precursor of cyclic dithioacetal (1,3-dithiane) derivatives of carbonyl compounds. The protection step is catalyzed by Lewis acids, e.g. BF3 etherate: Tetrahedron Lett., 871 (1971), TiCl4: Tetrahedron Lett., 24, 1289 (1983), Aluminum trifluoromethanesulfonate, B20785, or Indium(III)­ trifluoromethanesulfonate, 40131. Diothioacetalization can be accomplished under neutral, solvent-free conditions using Lithium trifluoromethanesulfonate, 39322, as catalyst: Tetrahedron Lett., 40, 4055 (1999).
