In search of an alpha(2)-antagonist/5-HT uptake inhibitor as a potential new class of antidepressant with a more rapid onset of action, compound 3 was prepared and observed to possess high affinity for the alpha(2)-receptor (K-i = 6.71 nM) and the 5-HT uptake site (20.6 nM). A series of tertiary amine analogs of 3 were synthesized and assayed for their affinity at both the alpha(2)-receptor and the 5-HT uptake site. The structure-activity relationship reveals that a variety of structural modifications to the arylethyl fragment are possible with retention of this dual activity. On the tetralin portion, 5-OMe substitution and the (R) stereochemistry at C-l are optimal with alternate substitutions producing compounds retaining high affinity for the alpha(2)-receptor but lacking affinity for the 5-HT uptake site. Data for several rigidified 5-O-alkyl analogs suggests that the favored orientation of the oxygen lone pairs may be away from the g-position of the tetralin.

Pd(II)-catalyzed intramolecular amination of arenes is developed using either a one- or two-electron oxidant. The reaction protocol tolerates a wide range of deactivating groups including acetyl, cyano, and nitro groups. This catalytic reaction allows expedient syntheses of broadly useful substituted indolines or indoles.
