Versuchsvorschrift
5α-Cholestan-3β-ol-selenobenzoate (278 mg, 0.50 mmol) was reacted with bis-(p-methoxyphenyl)-telluroxide for 0.3 h. 5α-Cholestan-3β-ol-benzoate (229 mg, 93%) was obtained after p.l.c. (petroleum ether-ethyl acetate 9:1). The product obtained was recrystallized from ethyl acetate (198 mg, 80%) m.p. 136°-137° (lit., 136°-137°).
