Abstract: C-Benzoyl-N-phenylnitrone reacts with dihydrothiophene derivatives (2,3-dihydro- and 2,5-dihydrothiophene) via 1,3-dipolar cycloaddition to give diastereoisomeric pair of exo- and endo-cycloadducts. In case of N-methylpyrrole a substitution product is formed. Thiophene and benzothiophene did not react with the above-mentioned nitrone, decomposition products of nitrone were formed only.
