14β‐Configurated Δ 8 ‐Ergostene Derivatives The 6‐oxo‐Δ 7 ‐steroid 1 undergoes deconjugation by treatment with NaOH (methanol, reflux) to give a mixture of the known Δ 8(14) ‐isomer 2 and the new 14β‐Δ 8(9) ‐isomer 3 (4:1); 3 was mainly formed by higher temperature (130°C: 80% 3 ). Huang‐Minlon reduction of 1 yields the stable 14β‐Δ 8(9) ‐ergostene derivative 5 .
