B. Schlummer et al., A new heterocyclic ring system in (4SR,6SR)-6-(2-phenylethyl)-4-phenyl-1,4,3-oxathiazin-2(6H)-one, ACT CRYST E, 57, 2001, pp. o252-o253
The title compound, C17H17NO2S, is formed by reaction of 2azidocarbonyloxy-
4-phenyl-1-thiophenylbutane with iron(II) chloride as catalyst. This is the
first example of the 1,4,3-oxathiazin-2(6H)-one ring system.
