2-phenylbenzo[B]furans, process for their manufacture and pharmaceutical preparations containing them

Abstract

The invention relates to new furans and thiophenes with the general Formula 1, ##STR1## in which R.sup.1 and R.sup.2 independently of one another denote a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, a benzyl group, a group C(O)R.sup.4, where R.sup.4 is an alkyl or alkoxy group having 1 to 10 carbon atoms or a phenyl radical, or a carbamoyl group --C(O)NR.sup.5 R.sup.6, where R.sup.5 and R.sup.6 independently of one another are a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, and n denotes an integer from 0 to 12 if R.sup.3 is a hydrogen atom, or n denotes an integer from 4 to 12 if R.sup.3 is an amino group --NR.sup.7 R.sup.8, where R.sup.7 and R.sup.8 independently of one another represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms or R.sup.7 and R.sup.8 together represent an alkylene group --(CH.sub.2).sub.m -- or the group --(CH.sub.2).sub.2 -- or R.sup.3 denotes an amide group --C(O)NR.sup.7 R.sup. 8, where R.sup.7 and R.sup.8 have the abovementioned meanings, or R.sup.3 denotes a sulphinyl group --S(O)R.sup.3, where R.sup.9 is the radical --(CH.sub.2).sub.m (CF.sub.2).sub.o CF.sub.3 and m and o are 2, 3, 4, 5 or 6 and x denotes an oxygen or sulphur atom. These new compounds are strong and selective anti-oestrogens, and have therapeutic applications in the treatment of oestrogen-related illnesses.
