  摘要：

  The synthesis of 1-phenylpiperazines, linked in the alpha or beta position of the tetralin moiety on the terminal part of the N-4 alkyl chain, and their radioligand binding affinities for 5-HT1A, 5-HT2A, D-1, D-2, alpha(1), and alpha(2) receptors along with SAR studies on the 5-HT1A receptor are reported. Several changes have been carried out on previous structures of type 2, by inserting the alkyl chain with variable length in the alpha or beta position of the tetralin moiety and by changing the position of the methoxy group on the aromatic ring of the tetralin nucleus. The highest affinity (IC50 = 0.50 nM) and selectivity for the 5-HT1A receptor were showed by 1-phenylpiperazine 2a with a three-membered alkyl chain bearing a 5-methoxytetralin-1-yl ring in the omega position.

  the C-H bond, which is diastereoselectively attacked, and steric strain between the remaining substituents at the stereogenic and the prostereogenic center is minimized. DFT calculations support this model. They suggest, however, that the reaction is not concerted but occurs via hydrogen atom abstraction and subsequent radical rebound. Further support for an antiperiplanar attack relative to a given
