New Synthesis with Elemental Sulfur. - Preparation of 1,2-Benzisothiazoles and Some Secondary Reactions

The preparation of new 1,2-benzisothiazoles 2,3,5 and of thienoisothiazole 4 is described.The thioethers 8 have been obtained from 2 and 3 by ring opening with alcoholate and reaction with halomethyl compounds.On cyclisation, the thioethers 8 give the thionaphthenes 11.The ring systems of thionaphthenopyrimidines 10 and 12 have been prepared from 11.
