Phenyl chlorothionoformate has been used in stereo directed synthesis of optically active, (-)-mintlactone, synthesis of peptide α-thioesters having a variety of C-terminal amino acids, synthesis of scyllo-inositol derivatives, thionocarbonylation of unprotected thymine nucleosides, preparation of phenoxythiocarbonyl esters of protected ribonucleosides. It is also used as a reagent in the thionocarbonylation of unprotected thymine nucleosides. It forms phenoxythiocarbonyl esters of protected ribonucleosides which can be reduced by tributyltin hydride to deoxyribonucleosides.


Moisture, Heat Sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Keep away from oxidizing agents. Stable under recommended storage conditions.

Aryl chlorothionoformates react with OH groups to give thiocarbonate esters. These have a much greater tendency to undergo cyclic elimination than their oxygen counterparts, with dehydration as the net result. Thus, e.g. oximes are dehydrated to nitriles under mild conditions: Chem. Commun., 1014 (1970):

Similarly, amides are dehydrated to nitriles, and formamides to isonitriles under mild conditions: Tetrahedron Lett., 40, 747 (1999).

Alcohols are converted to alkenes in better yields than in the Chugaev (xanthate pyrolysis) method, succeeding with hindered alcohols which do not readily form xanthates: J. Chem. Soc., Chem. Commun., 1215 (1972); Helv. Chim. Acta, 55, 2277 (1972). Secondary alcohols give thiocarbonate esters which can be reduced to alkanes by tributyltin hydride, in a useful deoxygenation sequence. For use in an enantiospecific synthesis of the antiviral agent ganciclovir phosphonate, see: J. Med. Chem., 37, 1371 (1994).
