Ten analogs of muscimol and thiomuscimol in which the amino function was delocalized in an amidinic system were prepared by N2 alkylation of 6-aryl-3-aminopyridazines with (chloromethyl)isoxazole or (chloromethyl)isothiazole derivatives. These muscimol and thiomuscimol derivatives show potent binding properties for GABA-A receptors (they displace [3H]GABA and [3H]gabazine) and provoke convulsions after

The route scouting and development activities toward a safe and scalable manufacturing route for 3-(3-methoxyisoxazole-5-yl) propanoic acid are outlined in this article. In a first step, methyl 3-hydroxy-5-isoxazolecarboxylate (CAS: 10068-07-2) was prepared on a kilogram scale via bromination of dimethyl fumarate under photoflow conditions followed by condensation with hydroxyurea. This intermediate
