摘要:
The present invention relates to methods for the production of E-1-�4'-(2-dimethylaminoethoxy)-phenyl!-1-(3'-hydroxyphenyl)-2-phenyl-1-butene of formula (I) which comprises heating the compound of formula (II) in the presence of an organic solvent and HCl gas and cooling the reaction to obtain the compound of formula (IIIa), and then heating the isolated compound of formula (IIIa) in the presence of sulfuric acid or hydrochloric acid to obtain the compound according to formula (I). ##STR1## where R is an easily hydrolyzable protecting group
摘要:
Para substituted benzoic acid derivatives of general formula (1) ##STR1## and their physiologically compatible salts, where R.sup.1 may be H, isopropyl, t-butyl p0 X may be ##STR2## and R.sup.2 may be --OH, --OR', where R' is a linear or branched, saturated or unsaturated C.sub.1 to C.sub.3 alkylmoiety, or a --NHCH.sub.2 COOH-- group, have hypolipedemic activity. They may be obtained by known methods either from the corresponding unsaturated ketones or from saturated hydroxycompounds, where the esterified benzoic acid moiety may be saponified or converted to a carboxymethylamide.

摘要:
Novel (E)-1-[4'-(2-alkylaminoethoxy)phenyl]-1- (3'-hydroxyphenyl)-2-phenylbut-1-enes of the general formula ##STR1## wherein R.sup.1 and R.sup.2 may be the same or different, provided that, when R.sup.1 and R.sup.2 are the same, each of them is a methyl or ethyl radical, and when R.sup.1 and R.sup.2 are different, one of them is hydrogen and the other is a methyl or ethyl radical, and the therapeutically compatible salts thereof, have a marked anti-estrogenic effect and are suitable for treating hormone-dependent mammary tumors.The compounds can be prepared by dehydrating carbinols of the general formula ##STR2## wherein R.sup.1 and R.sup.2 may be the same or different, provided that, when R.sup.1 and R.sup.2 are the same, each of them is a methyl or ethyl radical, and when R.sup.1 and R.sup.2 are different, one of them is a benzyl radical and the other is a methyl or ethyl radical; and wherein R.sup.3 is hydrogen or an easily hydrolyzable protecting group, through the action of mineral acid while removing any protecting group present, isolating through crystallization the E-form from the pair of isomers obtained, and removing by hydrogenolysis any benzyl group present.Compositions comprising the subject 1,1,2-triphenylbut-1-ene derivatives are described also. The corresponding novel 1,1,2-triphenylbut-1-ene derivatives having the (Z) configuration are also disclosed.
