Regioselective dehydrogenation of 3-keto-steroids to form conjugated enones using o-iodoxybenzoic acid and trifluoroacetic acid catalysis
Iida, Takashi,Omura, Kaoru,Sakiyama, Ryou,Kodomari, Mitsuo
, p. 45 - 51 (2014)
Mild and regioselective conversion of 3-keto-5α- and 3-keto-5β-steroids (trans A/B- and cis A/B-ring juncture, respectively) to the corresponding enones (Δ1- and Δ4-3- ketones) by treatment with o-iodoxybenzoic acid (IBX) catalyzed by trifluoroacetic acid (TFA) in DMSO, is described. The IBX-mediated reaction involved dehydrogenation of the α- and β-hydrogen atoms of the 3-ketones to give the enones regioselectively in good isolated yields without concomitant formation of related dienones and trienones.
OCCURRENCE OF 2-METHYL-, 3-METHYL- AND 6-METHYLTRIAROMATIC STEROID HYDROCARBONS IN GEOLOGICAL SAMPLES.
Lichtfouse, E.,Riolo, J.,Albrecht, P.
, p. 3937 - 3940 (2007/10/02)
Triaromatic steroid hydrocarbons bearing a methyl substituent at position 2, 3, or 6 have been identified in marine sediments and petroleums from the Paris basin by comparison with C21 (1, 2, 3), C27 (4) and C29 (5) synthetic standards.Due to their formation with depth they are useful for maturity studies.
