    摘要: New 11.beta.-phenyl-14.beta.H-steroids of general formula (I), where Z is an oxygen atom or the hydroxyimino-grouping N.about.OH, and M and N are either jointly a second compound or L is a hydrogen atom and M is an .alpha.-permanent hydroxy group and either A and B together are a second compound and D is a hydrogen atom, where R.sup.1 is a five or six-part heteroalkyl residue or a cycloalkyl, cycloalkenyl or aryl residue or A is a hydrogen atom and B and D together are a methylene bridge, where R.sup.1 besides the aforementioned residues may be a possibly substituted hydrocarbon residue with up to 10 C atoms, a possibly substituted amino group, a hydroxy or C.sub.1-8 alkoxy, mercapto or thioalkyl group, R.sup.2 is a methyl or ethyl residue, and R.sup.3 /R.sup.4 represents the usual combination of substituents on the C17 atom in steroid chemistry, having antigestagenic and other properties.
