9-BROMOPROSTAGLANDIN DERIVATIVES, PROCESS FOR THE PREPARATION THEREOF, AND USE THEREOF AS MEDICAMENTS

摘要

Tne invention relates to compounds of Formula I (I) , wherein the 9-bromine atom can be in the .alpha.- or .beta.-position, R1 is the residue CH2OH or where R2 means a hydrogen atom or an alkyl, cycloalkyl, aryl, or heterocyclic residue; or R1 is the residue where R3 means an acid residue or the residue R2; and A is a -CH2-CH2- or cis-CH=CH-group, B is a -CH2-CH2-, a trans-CH=CH-, or a -C?C-group, W is a free or functionally modified hydroxymethylene group or a free or functionally modified ? group wherein the OH-group can be in the .alpha.- or .beta.position, D and E together mean a direct bond or D is a straight-chain, branched-chain, or cyclic alkylene group of 1-10 carbon atoms optionally substituted by fluorine atoms, and E is an oxygen or sulfur atom, a direct bond, a -C?C-bond, or a -CR6=CR7-group wherein R6 and R7 are different from each other and represent a hydrogen atom, a chlorine atcm, or a C1-C4-alkyl group, R4 is a free or functionally modified hydroxy group, R5 is a hydrogen atom, an alkyl group, a halosubstituted alkyl group, a cycloalkyl group, an optionally substituted aryl group, or a heterocyclic group; and, if R2 means a hydrogen atom, the salts thereof with physiologically compatible bases, their preparation, and their use, for example, as abortifacients. .1.
