摘要：
23-Oxa-derivatives in the vitamin D series of formula I ##STR1## are described in which R.sup.1, R.sup.2 and R.sup.4 independently of one another mean a hydrogen atom or an acyl group with 1 to 9 carbon atoms,R.sup.3 each means a hydrogen atom or each a linear or branched alkyl group with 1 to 4 carbon atoms and X means an alkylene radical--(CH.sub.2).sub.n -- with n=1, 2, 3, and if n=1, R.sup.3 each cannot be a methyl or propyl group, as well as a process for their production.The compounds have proliferation-inhibiting and cell-differentiation effects and are suitable for the production of pharmaceutical agents.
