    摘要: The new intermediate products of general formula I ##STR1## in which R.sup.1 stands for a hydrogen atom or a straight-chain or branched alkyl group with 1 to 4 carbon atoms,R.sup.2 stands for a hydrogen atom or a methyl group,R.sup.3 stands for a hydrogen atom,R.sup.4 stands for an acyloxy group with 1 to 4 carbon atoms in the acyl radical orR.sup.3 and R.sup.4 together stand for a keto-oxygen atom, are suitable in an excellent way for introducing a .DELTA..sup.1 double bond in the steroid skelton with the simultaneous presence of a .DELTA..sup.4 double bond, as well as a saturated carbonyl group, by clevage of hydrogen iodide with a base in an amidic solvent at elevated temperature. If R.sup.2 stands for a hydrogen atom, the A-ring is aromatized after the hydrogen iodide cleavage. For the production of a new intermediate products, special iodization processes, which partially also allow a stereoselective control of the iodization, are used.
