The reaction between 1,1-dithioalkyl phenyl sulphones (11) and ethyl 4-bromobutyrate affords tetrahydro-2-furylidene derivatives (13) together with minor amounts of the cyclopropyl ketones (15).A mixture of the cyclohexanone and dihydropyran derivatives (17) and (18), respectively, is obtained by the reaction of (11) with ethyl 5-bromovalerate.Treatment of the ω-bromo-β-ketosulphone (19) with various basic reagents also gives a mixture of (17) and (18).
