✦ Synopsis

Recently we have shown that appropriately substituted cyclic sulfoxides when subjected to the Pumerer reaction undergo loss of the elements of water to form highly reactive heterocyclic species containing tetravalent sulfur.l** Thus, naphtho[l,8-cdlthiapyran (I) and acenaphtho-[5,6-cdlthiapy-ran (II), isoelectronic analogues of the aromatic hydrocarbons &-cycloheptanaphthalene iIIIj3 and &-cycloheptaacenaphthene (IV),3 have been generated in good yield from their corresponding sulfoxides.
