Herein we report the use of metathesis to construct a novel tetracyclic core in a series of estrogen receptor degraders. This improved the chemical stability, as assessed using an NMR-MS based assay, and gave a molecule with excellent physicochemical properties and pharmacokinetics in rat. X-ray crystallography established minimal perturbation of the bridged compounds relative to the unbridged analogues in the receptor binding pocket. Unfortunately, despite retaining excellent binding to ERα, this adversely affected the ability of the compounds to degrade the receptor.
