    Description / Table of Contents: Polycyclic Compounds, XVI.  -  9,10-Diheterosubstituted Hexahydrophenanthrenones via Oxanorbornadiene Bridge Opening with Potassium ThiocyanateHerrn Professor Dr. Horst Pommer mit allen guten Wünschen zum 60. Geburtstag gewidmet.The reaction of oxanorbornadiene 1 with potassium thiocyanate in the presence of mineral acid leads primarily to trans-9-hydroxy-9-methyl-10-thiocyanato-3,4,9,10-tetrahydrophenanthrene-1-(2H)-one (2a) in good yield. The subsequent reactions of 2a to give further 9,10-disubstituted hexahydrophenanthrenones are discussed. Structural assignment of the new compounds is primarily based on their 13C-NMR-spectra.
    Notes: Die Umsetzung des Oxanorbornadiens 1 mit Kaliumthiocyanat in Gegenwart von Mineralsäure führt zunächst in guter Ausbeute zu trans-9-Hydroxy-9-methyl-10-thiocyanato-3,4,9,10-tetra-hydrophenanthren-1(2H)-on (2a), dessen Folgereaktionen zu weiteren 9,10-diheterosubstituierten Hexahydrophenanthrenonen besprochen werden. Die Strukturermittlung der neuen Verbindungen erfolgt insbesondere mit Hilfe ihrer 13C-NMR-Spektren.
