Abstract

Described herein are compounds that are estrogen receptor modulators of Formula (I):

and stereoisomers, tautomers, or pharmaceutically acceptable salts thereof, wherein SERMF is a selective estrogen receptor modulator fragment and with the substituents and structural features described herein. Also described are pharmaceutical compositions and medicaments that include the compounds described herein, as well as methods of using such estrogen receptor modulators, alone and in combination with other compounds, for treating diseases or conditions that are mediated or dependent upon estrogen receptors.
