Die Röntgenstrukturanalyse von 17β‐Bromacetoxy‐ 9β, 10α‐androst‐4‐en‐3‐on

Abstract

1) Die Formeln dieser Alkaloide sind unter [3] zu finden.

The crystal and molecular structure of 3β,17α-dihydroxy-16β-bromo-5α-pregnan-11,20-dione and its comparison with the related -l6β-bromo-3β-acetate and -2l-bromo-3β-ol steroids

“…Angle C(14)-C(13)-C(17) has an average value of 99.7 + 0.8 o and the remaining angles in this ring have an average value of 104.8 +0.9 ° , with no significant variations observed. Values similar to these have been observed in other steroids, such as androsterone (High & Kraut, 1966) and 17fl-bromoacetoxy-9fl, 10e-androst-4-en-3-one (Oberhansli & Robertson, 1967).…”
