    Description / Table of Contents: [4 + 2]-Cycloaddition Products of Perfluoroorgano-N-sulfinylamines and their OxidationPerfluoroorgano-N-sulfinylamines 1a-c (Rf—NSO, Rf=CF3, C6F5, CF3CO) react with dimethylbutadiene as an example of an activated diene under formation of 3,6-dihydro-4,5-dimethyl-2H-1,2-thiazine 1-oxides 2a-c. By oxidation of 2a and 2b with mCPBA the epoxide 4a and the epoxysultames 5a and 5b, respectively, are obtained. The pyrrole 3b is formed by alkaline hydrolysis of 2b.
