| Abstract: | Cycloaddition of dienes to thiophene dioxides affords mono-and bisadducts, depending on the reaction conditions. Regio-and
stereochemical specific features of the cycloaddition were revealed. The thermal rearrangement of the monoadduct was found.
Dedicated to Academician N. S. Zefirov on the occasion of his 70th birthday.
