摘要:
New 9-alphahydroxy steroids are prepared by the introduction of substituents on the D-ring of 9-alpha-hydroxy-androst-4-ene-3,17-dione. The resulting compounds are useful intermediates in the synthesis of corticosteroids.
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.
摘要:
Known pregnane derivatives are prepared by esterification of know androstane derivatives to give new esters of Formula III ##STR1## wherein in each case symbolizes a single bond or a double bond,n is 1 or 2,R.sub.1 is hydrogen or methyl,R.sub.2 is hydrogen or formyl, andR.sub.3 is chlorine, hydroxy or an alkanoyloxy group of up to 6 carbon atoms,and reaction of the latter with Ag(I) and formic acid.
摘要:
Oxymercuration reaction products (I) and/or mercury contaminated steroids (I) are purified by dissolving the compound in a suitable solvent and contacting with a metal dust selected from zinc, copper or iron and a suitable acid.
