Three synthetic routes towards a novel estrogen receptor ligand template based on a rigid bicyclo-[3.3.1]-nonene core have been investigated. The prototype compound exhibits potent binding at the ERbeta receptor and promising estrogen receptor subtype selectivity. (C) 2003 Elsevier Science Ltd. All rights reserved.

Treatment of ω-substituted1-alkynes (2) with 2 equiv. of trimethylstannylcopper–dimethylsulphide (1) in tetrahydrofuran (–63 ° C)in the presence of 60 equiv. of methanol affords good to excellent yields of the corresponding 2-(trimethylstannyl)-1-alkenes (3).
