摘要:
1,1-dialkoxy- or 1,1-(.alpha.,.omega.-methylenedioxy)-non-2-yn-9-ol and their OH-protected derivatives of the general formula I ##STR1## where R.sup.1 and R.sup.2 are each C.sub.1 -C.sub.6 -alkyl or together form an alkylene chain of 2 to 5 carbon atoms and X is hydrogen or a protective group which can be eliminated, their preparation and their use as intermediates.
