(1S,2R)-8-Hydroxy-1-methyl-2-(dipropylamino)tetralin [(1S,2R)-3] has been previously characterized as a selective and potent but partial 5-HT1A-receptor agonist. In the present study, we have prepared derivatives of (1S,2R)- and (1R,2S)-3 in which various C8-substituents have been introduced. In addition, the enantiomers of the N-isopropyl-N-n-propylamino derivative of 3 were prepared. The new derivatives
