Abstract
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.
