ring retain gastric activity. Of these 2-substituted compounds, the 2 alpha, 9a alpha isomer has potentselectivegastricprokinetic activity with only weak dopamine antagonist properties. Spectroscopic data show that the quinolizidine ring preferentially adopts a trans chair-chair conformation with an axial benzamide moiety. However, energy calculations indicate that, at nondopaminergic receptors controlling
