The present invention provides compounds of Formula I,
pharmaceutical compositions comprising these compounds and methods of using these compounds to treat or prevent a disease or disorder mediated as FXR modulators. Specifically, the present invention relates to isoxazole derivatives useful as agonists for FXR, and methods for their preparation and use.
the synthesis of 2,5-disubstitutedoxazolesvia iodine-promoted oxidative domino cyclization. These reactions were performed with readily available methyl azaarenes and α-amino ketones under metal-free conditions. This protocol is a simple method with high functional group compatibility, a wide range of substrates, and excellent yield, providing a new way to synthesize azaarene-attached oxazoles.
