Reaction of manganic acetate with organic disulphides in dichloromethane-trifluoroacetic acid in the presence of a variety of unsaturated amides leads to intramolecularcyclisation with formation of sulphenylated oxazolines, oxazines or tetrahydropyrroles.

using electrophilic cyclization of allylic amide is a simple and powerful method. However, cyclization involving arylsulfenylation requires harsh reaction conditions. We found that the reaction proceeds under mild heating conditions with the combination of a Bronsted acid and tetrabutylammonium chloride. This method enabled the synthesis of 5-[(arylsulfenyl)methyl]oxazoline derivatives under mild conditions
