Studies toward the total syntheses of heterocyclic analogues of adriamycin

The design and synthesis of two heterocyclic thioanalogues of 7-deoxy daunomycinone, 9-acetyl-6,9,11-trihydroxythioxantho{2,3-g}- and -{3,2-g}tetralin, was accomplished. Various synthetic methodologies to accomplish this were evaluated and two key steps necessary for this synthesis were developed. The first consisted of a novel annulative synthetic sequence utilizing a biacetyl synthon, 3,3-diethoxy-2-butanone cyclohexylimine, and an ortho bis-halomethylarene. The second consisted of the use of o-chlorosulfenylbenzoyl chloride as a thiosalicyclic acid equivalent. Model studies toward the further elaboration of these 7-deoxy aglycones to the active glycosides were also studied. / In addition, 1-{{2-{(2-dydroxyethyl)amino}ethyl}amino}-4-hydroxythioxanthone was prepared and found not to have antitumor properties against P-388 leukemia in vivo.
