By reaction of 1,2-benzooxathiin-4(3H)-one 2,2-dioxide (II) with mercaptopropionic acid the new tricycle 4-oxo-3,4-dihydro-2H-thiopyranobenzooxathiin 5,5-dioxide (IV) together with tetracycle V and pentacycle VII were obtained.The key ketone IV was then converted to β-diketone IX, enamino ketone XVI and α-bromoketone XX intermediates to give with nucleophilic reagents 7,11-dithiaoxasteroids analogues.
