N,N-Dialkylaminosulfur Trifluoride Dethiofluorination

N,N-Dialkylaminosulfur trifluorides are useful not only as deoxofluorination reagents but also as dethiofluorination reagents. Thus, the dialkylaminosulfur trifluorides reacted with organosulfur compounds such as thioesters, thioketones, etc. to give the corresponding dethiofluorinated compounds [1, 2]. On the other hand, a similar sulfur-mediated fluorination methodology was successfully applied to synthesize glycosyl fluorides, which were very useful synthetic intermediates in oligosaccharide chemistry [3, 4, 5, 6, 7, 8, 9].
