|Title:||Esters of p-carbonylphenoxy-isobutyric acids|
|Abstract:||This invention is concerned with esters of p-carbonylphenoxy-isobutyric acids of the general formulae: ##STR1## wherein R is a phenyl group substituted by one or two halogen atoms; R' is H, CH.sub.3, C.sub.6 H.sub.5, SCH.sub.3, OCH.sub.3, or, SO.sub.2 CH.sub.3 ; R" is CH.sub.3 or C.sub.2 H.sub.5 ; Y is C.sub.1 -C.sub.4 alkoxy, phenoxy, phenoxy substituted by one or two halogen atoms, or, OCH.sub.2 O--CO--C(CH.sub.3).sub.3 ; Z is C.sub.1 -C.sub.4 alkyl, phenyl or R; NR.sub.1 R.sub.2 is N(CH.sub.3).sub.2 N(C.sub.2 H.sub.5).sub.2, morpholino, piperidino, hexamethylenimino, pyrrolidino. This invention is also concerned with acid addition salts obtained from formula Ia compounds with acids. Compounds of formulae I and Ia are useful as hypocholesterolemiant and hypolipidemiant agents.|
|Inventor(s):||Mieville; Andre (Lausanne, CH)|
|Assignee:||Orchimed SA (CH)|
|Filing Date:||Sep 01, 1977|
|Claims:||1. A novel ester of p-carbonylphenoxy-isobutyric acid selected from the group consisting of |
(a) compounds of the formula ##STR18## wherein R' is H, CH.sub.3, C.sub.6 H.sub.5, SCH.sub.3, OCH.sub.3, or SO.sub.2 CH.sub.3 ;
R" is CH.sub.3 or C.sub.2 H.sub.5 ;
Z is a phenyl group substituted by one halogen atom and
NR.sub.1 R.sub.2 is N(CH.sub.3).sub.2, N(C.sub.2 H.sub.5).sub.2, morpholino, piperidino, hexamethylenimino or pyrrolidino, and
(b) non-toxic acid addition salt thereof.
2. A novel ester of p-carbonylphenoxy-isobutyric acid having the formula ##STR19## wherein Z is a 4-chlorophenyl group, and NR.sub.1 R.sub.2 is N(C.sub.2 H.sub.5).sub.2, morpholino, piperidino or hexamethylenimino; and its non-toxic acid addition salts.
3. A novel ester of p-carbonylphenoxy-isobutyric-acid having the formula ##STR20## wherein Z is C.sub.1 -C.sub.4 alkyl, phenyl or chlorophenyl and NR.sub.1 R.sub.2 is a hexamethylenimino group and non-toxic acid addition salts thereof.
