Electron-impact Induced and Thermal Decomposition of Dithranol Derivatives, I: Thermolysis of 10-Phenylthio-dithranol in the Mass Spectrometer

Zusammenfassung

Dithranol (anthralin; 1,8-dihydroxy-9-anthrone) and its derivatives bearing
a variety of substituents in the 10-position are of actual interest in research
on psoriasis1). In connection herewith 10-alkylthio- and 10-arylthio-1,8-
dihydroxy-9(10H)-anthracenones were synthetized and used for antipsoriatic
activity2,3).
