Abstract
Reaction of arylsulfinyl and arylthio acetonitriles (1) with phenyl is othiocyanate in the presence of sodium hydride and subsequent alkylati on lead to the ketene S,N-acetals (3a-h). Using methyl bromoacetate as alkylating agent thiazolidones (4a-c) are formed whereas phenacylbrom ide gives the 4-hydroxythiazolidines (5a-f). In an analogous way arylt hio and arylsulfinyl acetophenones (6) react with phenyl isothiocyanat e yielding S,N-acetals (7a-e).
