Amberlyst 15 is also effective: Synthesis, 1826 (2001), as is In(OTf)3: Synlett, 1535 (2002). 1,3-Oxathiolanes can be prepared from acid-sensitive aldehydes with LiBH4 as catalyst in acetonitrile: Synlett, 238 (2001). Cleavage can be effected, e.g. with chloramine-T: Tetrahedron Lett., 3445 (1971), isoamyl nitrite: Tetrahedron. Lett., 3561 (1978), or periodic acid: Tetrahedron Lett., 37, 4331 (1996). Selective cleavage of oxathiolanes in the presence of dithiolanes has been achieved with triphenylcarbenium tetrafluoroborate: J. Chem. Soc., Perkin 1, 542 (1972), or 4-nitrobenzaldehyde catalyzed by TMS-OTf: J. Chem. Soc. Chem. Commun., 1937 (1994). Compare 1,2-Ethanedithiol, L12865.
