Article abstract of DOI:10.1055/s-1994-25639

By cycloaddition reactions of the title compounds 1, new spiro[1,3-dithiole-thiopyran] derivatives 3 and 5 are available. Their cleavage with mercury(II) acetate leads to the corresponding bicyclic thiopyran-4-ones 9 and 10. Starting from 3H,6H-[1,2]dithi
