Described herein are tetrahydro-pyrido[3,4-b]indol-1-yl compounds with estrogen receptor modulation activity or function having the Formula I structure: and stereoisomers, tautomers, or pharmaceutically acceptable salts thereof, and with the substituents and structural features described herein. Also described are pharmaceutical compositions and medicaments that include the Formula I compounds, as well as methods of using such estrogen receptor modulators, alone and in combination with other therapeutic agents, for treating diseases or conditions that are mediated or dependent upon estrogen receptors.
3-benzyloxy-1-isocyanopropenes. Synthesis and use as 3-hydroxypropanoyl anion equivalents
New acyl anionequivalents bearing a hydroxyl group at the β-position have been developed. Treatment of 3-benzyloxy-1-isocyanopropenes with lithium diisopropylamide (LDA) in THF at −78 °C generated the 1-lithio compounds, which reacted with alkyl halides to afford the corresponding 1-alkylated products in good yields. Acid hydrolysis of these alkylated products followed by hydrogenolysis of the resulting
