The syntheses of 3,4-dihydro-2H-1,5,2-benzo[f]dithiazepin-3-one 1,1-dioxides (8-11, 14, 17-20) and corresponding 1,1,5,5-tetraoxides (12, 13) are described. Reactivity of these compounds in their alcoholysis, alkaline hydrolysis and alkylation is also reported. Evaluation performed at the US National Cancer Institute (Bethesda) revealed the in vitro antitumor activity of 7-chloro-3,4-dihydro-8-methyl-4-phenyl-2H-1,5,2-benzo[f]dithiazepin-3-one 1,1-dioxide (11).
