Some Photochemical Studies on the Natural Sapogenin "Diosgenin"
Photooxygenation reactions of diosgenin (t) in the presence of TPP (tetraphenylporphin) or RB (rose bengal) as singlet oxygen sensitizers in different solvents gave 5-hydroperoxy-spirost-6enne-3β-01 (2). Photo-rearrangement of 2 in benzene gave spirost-5-ene-3β-ol-7-one (3), whereas in ethanol the furostane derivative (4) was obtained.
