Our endeavor toward the identification of potent and safe CRTH2 receptor antagonists starting from setipiprant (ACT-129968) is reported. An unexpected and surprising discovery was that all unwanted safety issues observed with the very potent antagonist (S)-B-1 (ACT-453859) could be overcome by the replacement of one aromatic CH group by an aromatic nitrogen atom to result in (S)-72 (ACT-774312) which

The scope and limitations of Pd(0)-catalyzed intramolecular coupling of amino-tethered vinyl halides and ketone enolates as a methodology for the synthesis of nitrogenheterocycles have been studied. This reaction constitutes a synthetic procedure to obtain bridged, condensed, and monocyclic nitrogen-containing compounds.
