摘要:
The invention relates to a process for the production of prostaglandin precursors of formula I ##STR1## as well as their enantiomers in which X is A--W or W--A,A is a --C.tbd.C-- group,W is a hydroxymethylene group, in which the OH group can be functionally modified by etherification or esterification,D is a straight-chain or branched-chain alkylene group with 2-5 C atoms each or a ##STR2## group, n i s 1 to 3,E is a --C.tbd.C-- group or a --CR.sub.3 .dbd.CR.sub.4 group with R.sub.3 and R.sub.4 each meaning a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group,R.sub.1 is a hydrogen atom or a hydroxy group, which can be functionally modified as in W,R.sub.2 is a straight-chain or branched-chain alkyl group with 1-7 C atoms, characterized in that vinyl bromides of formula II ##STR3## in which Z means the group ##STR4## and R.sub.1, W, D, E and R.sub.2 have the above-indicated meanings and hydroxy groups unprotected in R.sub.1 and W or represented by an optionally substituted benzoyl radical, a C.sub.1 -C.sub.6 alkanoyl group, a tetrahydropyranyl radical, a tetrahydrofuranyl radical, a trialkylsilyl group or a diphenylalkylsilyl group each with alkyl meaning a C.sub.1 -C.sub.4 alkyl, are reacted with anhydrous cesium acetate in the presence of 18-crown 6.
