Nra. Beeley et al., A GENERAL-SYNTHESIS OF N-SUBSTITUTED ISOTHIAZOL-3(2H)-ONES, Journal of the Chemical Society. Perkin transactions. I, (16), 1994, pp. 2245-2251
A general route to the synthesis of N-substituted isothiazol-3(2H)-one
s (4a-i) is described which proceeds via trichloroacetic acid-mediated
ring closure of N-substituted (Z)-3-(benzylsulfinyl) propenamides (15
a-i).
