    Description / Table of Contents: 14β-Hydroxysteroids, II.  -  The Prins Reaction of Lumihecogenin AcetatePhotochemical rearrangement of hecogenin acetate (1) into the unsaturated aldehyde 5 followed by a Prins reaction leads efficiently to the 14β-hydroxysteroids 7a and 10a. The configuration of 7a, 10a, and 9a at C-13 and C-14 has been determined by chemical correlation and spectroscopically (1H-NMR, 13C-NMR, CD).
    Notes: Durch photochemische Umlagerung von Hecogeninacetat (1) zum ungesättigten Aldehyd 5 und anschließende Prins-Reaktion sind die 14β-Hydroxysteroide 7a und 10a bequem zugänglich. Die Konfiguration an C-13 und C-14 bei 7a, 10a und 9a wurde chemisch und mit Hilfe spektroskopischer Methoden (1H-NMR, 13C-NMR und CD) abgeleitet.
