M. Joselevich et al., SYNTHESES OF 6,19-OXIDO-BRIDGED ANALOGS OF 11-BETA,17-ALPHA-DIHYDROXYPROGESTERONE AND 11-KETO-17-ALPHA-HYDROXYPROGESTERONE, Anales de la Asociacion Quimica Argentina, 85(3-4), 1997, pp. 117-121
11 beta, 17 alpha-Dihydroxy-6,19-oxidoprogesterone (1) and 11-keto-17
alpha-hydroxy-6,19-oxidoprogesterone (2) were synthesized from readily
available materials. C-19 functionalization was accomplished with the
mercuric oxide/iodine system under irradiation with visible light.
