Treatment of 5α,6α-epoxy-3β-methylsulphonyloxyandrostan-17-one with lithium bromide and lithium carbonate in dimethylformamide afforded androst-4-ene-6,17-dione. Dehydrogenation of this with… Expand
Applications of chromium(II) chloride. Part V. The reduction of some nitro-steroids
Chromium(II) chloride has been shown to reduce 6-nitro-, 17-nitro-, and 3,3-dinitro-steroids to the corresponding oximes. On the other hand the βγ-unsaturated 6-nitrocholest-4-enes afford the… Expand
Circular dichroism, nuclear magnetic resonance, and crystal structure of 4 alpha-bromo-5 alpha-androst-2-ene-1,17-dione.
VERWENDUNG VON CHROM(II)‐CHLORID 5. MITT. RED. EINIGER NITROSTEROIDE
Cr(II)-chlorid reduziert in Aceton das 6-Nitro-(I), 17-Nitro-(II) bzw. 3,3-Dinitrosteroid (III) zu den entsprechenden Oximen.
The mechanism of a steroidal aromatization reaction.
The aromatization of 3β-hydroxyandrost-5-en-17-one with 1,3-dibromo-5,5-dimethylhydantoin has been shown to involve migration of the C-9(10) bond rather than methyl migration.
Circular dichroism, nuclear magnetic resonance, and crystal structure of 4α-bromo-5α-androst-2-ene-1,17-dione
The stereochemistry of the bromination of 5α-androst-2-ene-1,17-dione with N-bromosuccinimide has been established by examination of the circular dichroism, nuclear magnetic resonance, and crystal… Expand
