  A novel synthesis of 7-aryl-8-fluoro-pyrrolo[1,2-a]pyrimid-4-ones as potent, stable GnRH receptor antagonists

  摘要：

  A new class of small molecule GnRH antagonists, the 7-aryl-8-fluoro-pyrrolo[1,2-a]pyrimid-4-ones, was designed and a novel synthesis for these compounds was developed. The synthesis utilizes a base-catalyzed intramolecular cyclization of fluoromethyl pyrimidone 5 to generate the bicyclic core. Amongst the compounds synthesized, we discovered some highly potent GnRH receptor antagonists (e.g., 12. K-i = 9 nM), which showed enhanced stability towards acidic physiological conditions compared to the des-fluoro analogues. (C) 2002 Elsevier Science Ltd. All rights reserved.
