formed, resulting in rearranged 1,4-diazepanes and piperazines as side products. 1,2-anellated piperazines 15, 18 and 19 were prepared by hydrogenation of the alpha,beta-unsaturated ester 13 and by condensation of the primary amine 16b with formaldehyde, respectively. Receptor binding studies with radioligands revealed that the phenylacetamide 17b interacts with moderate affinity (K(i) = 181 nM) and considerable
为了找到新的受体配体,在哌嗪5的3位侧链中引入了各种取代基。在亲核取代过程中形成了5个氮丙啶鎓离子的羟基,导致重排的1,4-二氮杂庚烷和哌嗪作为副产物。通过α,β-不饱和酯13的氢化和伯胺16b与甲醛的缩合制备1,2-带芳基的哌嗪15、18和19。用放射性配体进行的受体结合研究表明,苯基乙酰胺17b以中等亲和力(K(i)= 181 nM)相互作用,并与sigma(1)受体具有相当大的选择性。
