Thioxanthenone, 10,dioxides, on treatment with sodamide in liquid ammonia, undergo a novel ring expansion to give dibenzo[b,f][1,4]thiazepinone 5,5-dioxides 〈75JHC〉. The thiazolium salt () undergoes base-induced ring expansion to give () 〈80TL〉, a direct parallel of the conversion of analogous oxazolium.

Justus Liebigs Annalen der Chemie, (1). pp. Abstract. Chemistry has been developed that allows for the synthesis of a series of novel tricyclic thioxanthenone,dioxides. A regioselective synthesis of the novel core substrate 3-chlorothioxanthenone,dioxide was achieved in 85% yield over three steps without the need for chromatographic by: 2.

Recently, thioxanthone derivatives were found to protect cells against toxic P-glycoprotein (P-gp) substrates, acting as potent inducers/activators of this efflux pump. The study of new P-gp chiral modulators produced from thioxanthone derivatives could clarify the enantioselectivity of this ABC transporter towards this new class of modulators. The aim of this study was to evaluate the P-gp Cited by: 4.
