• PubMed Abstract: 
  

  A series of estrogen receptor ligands based on a 3-alkyl naphthalene scaffold was synthesized using an intramolecular enolate-alkyne cycloaromatization as the key step. Several of these compounds bearing a C6-OH group were shown to be high affinity ligands. All compounds had similar ERalpha and ERbeta binding affinity ranging from micromolar to low nanomolar.
