Abstract

The pharmacological activities of the GABA agonist muscimol (1) and its dihydro analogue (2) have been shown to be almost identical. The closely related 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol (THIP, 3), although biologically less active than muscimol, was selected for clinical trials. We report the synthesis of the so far elusive cis-2,3,3a,4,5,6,7,7a-octahydro-3-oxoisoxazolo[5,4-c]pyridine (cis-DH-THIP, cis-4), which--surprisingly--is devoid of any GABAergic activity.
