Conformational energy calculations using the Molecular Mechanics II (MM2) program have been performed on 2‐aminotetrahydronaphthalene (ATN) and 2‐aminoindan derivatives which are active or inactive at dopamine receptors. The results were used to test a stereochemical and conformational model previously proposed for dopaminergic activity. The conformer predicted to be optimal for agonist activity was found to have relatively low energy (<1.5 kcal/mol) for all of the agonists examined. The model successfully: (1) explained the relative activity or inactivity of compounds such ascis‐ andtrans‐1‐methyl‐5‐hydroxyl ATN derivatives and the correspondingcis‐ andtrans‐octohydrobenzo[f]quinolines; (2) predicted the more potent antipode of 2‐aminoindan dopaminergic agonists; and (3) explained the structure‐activity peculiarities of 3‐(3‐hydroxyphenyl)‐N‐alkylpiperidines in which the potency is increased for (3S)‐isomers and decreased for (3R)‐isomers when theN‐alkyl group is greater than propyl. Predictions of postsynaptic dopaminergic antagonism were also made for some of the compounds. In agreement with previous conclusions, the inactivity of ATN derivatives with a 2‐methyl or 5‐propyl group was attributed to steric interference at the receptor since those groups did not have a significant conformational effect on the receptor ligand.
