    Eliminierungsreaktionen und Umlagerungen bei 14β-Hydroxy-12-sulfonyloxy-Steroiden (1988)

    Description / Table of Contents: Elimination Reactions and Rearrangement of 14β-Hydroxy-12-sulfonyloxy SteroidsElimination of 12α- or 12β-(methylsulfonyloxy)-14β-hydroxy steroids proceeds under rearrangement of the steroid nucleus. From the 12α-sulfonyloxy compound of 19 the (12βH)-14(13→12)abeo-13(18)-ene steroid 21 is obtained, whereas the 14β-hydroxy-(12βH)-17(13→12)abeo-13(18)ene compounds 14, 20 result from the 12β-methylsulfonyloxy derivatives of the steroids 13, 18. Structures were determined by means of 2D-NMR analyses and decoupling experiments. The theoretical explanation of this rearrangement leads to the possibility of an elimination of the 12α-methylsulfonyloxy group to yield the Δ11-alkene (28). This is possible by steric fixation of the migrating C-atoms at positions 14 and 17 in the 20,14β-lactone (26, 27).
    Notes: Eliminierung der 12α- oder 12β-Methylsulfonyloxy-Gruppe in 14β-Hydroxy-Steroiden erfolgt unter Umlagerung des Steroidgerüstes. Hierbei entsteht aus der 12α-Sulfonyloxy-Verbindung von 19 das 14β-Hydroxy-(12β-H)-14(13→12)abeo-13(18)en-Steroid 21, während die 14β-Hydroxy-(12βH)-17(13→12)abeo-13(18)-en-Verbindungen 14, 20 aus 12β-Mesyloxyderivaten der Steroide 13, 18 erhalten werden. Die Strukturbestimmung wurde mit 2D-NMR-Spektroskopie und Entkopplungs-Experimenten durchgeführt. Das theoretische Verständnis dieser Umlagerungen ergibt die Möglichkeit, durch Eliminierung der 12α-Mesyloxy-Gruppe auch Δ11-Steroide (28) zu erhalten. Hierzu müssen die wanderungsfähigen C-Atome an Position 14 und 17 im 20,14β-Lacton (26, 27) sterisch fixiert sein.

    Notes: The crystal structure of palmarin (1) has been determined by X-ray diffraction. The ring C conformation was confirmed to be that of a half chair, and the same result was obtained from 1H-NMR spectrometry. The ring C of chasmanthin (2) and glucosides of 1 and 2 (palmatoside A, and B) was also decided as a half boat by analysis of the 1H-NMR spectra.
