The present invention provides novel, reduced benzothiophenes of formula I ##STR1## wherein R is --H, --OH, --O(C.sub.1 -C.sub.4 alkyl), --O--CO--(C.sub.1 -C.sub.6 alkyl), --O--CO--Ar in which Ar is optionally substituted phenyl, or --O--SO.sub.2 --(C.sub.4 -C.sub.6 alkyl); R.sup.1 is --H, --OH, --O(C.sub.1 -C.sub.4 alkyl), --O--CO--(C.sub.1 -C.sub.6 alkyl), --O--CO--Ar in which Ar is optionally substituted phenyl, --O--SO.sub.2 --(C.sub.4 -C.sub.6 alkyl) chloro or bromo; n is 2 or 3; and R.sup.2 and R.sup.3 each are independently C.sub.1 -C.sub.4 alkyl, or combine to form 1-piperidinyl, 1-pyrrolidino, methyl-1-pyrrolidino, dimethyl-1-pyrrolidino, 4-morpholino or 1-hexamethyleneimino; or a pharmaceutically acceptable salt thereof. Further provided are methods for alleviating the symptoms of post-menopausal syndrome, and inhibiting endometriosis, uterine fibrosis, and aortal smooth muscle cell proliferation. Also provided are pharmaceutical formulations with formula I compounds, optionally including estrogen or progestin, and intermediate compounds.
