Treatment of N-substituted (Z)-3-(benzylsulfanyl)propenamides (4) with phenyliodine(III) bis(trifluoroacetate) containing trifluoroacetic acid resulted in an interrupted Pummerer-type reaction to give N-substituted isothiazol-3(2H)-ones (5) rather than the normal Pummerer-type products.
N-取代的 (Z)-3-(苄基硫烷基)丙烯酰胺 (4) 用含有三氟乙酸的苯碘 (III) 双(三氟乙酸) 处理导致中断的 Pummerer 型反应得到 N-取代的异噻唑-3(2H)- (5) 而不是普通的 Pummerer 型产品。
