从蛋白质氨基酸(S)-丝氨酸出发,合成了2位带有羟甲基残基的手性非外消旋1,4-二氮杂环庚烷4,并对其进行了结构表征。合成中的关键步骤是通过氯丙酰胺7与伯胺的连续亲核取代和分子内氨解形成双环体系8。两个反应步骤都需要用刘易斯酸Ti(O-iPr)4催化。哌嗪与1,4-二氮杂环庚烷环的同源化使σ 1受体亲和力和σ1/σ 2选择性显著提高。1,4-二苄基衍生物4a与σ 1受体相互作用的Ki值为7.4nM,对σ 1受体的选择性是对σ 2受体的53倍。
Starting from the proteinogenic amino acid (S)-serine chiral non-racemic 1,4-diazepanes 4 with a hydroxymethyl residue in position 2 are synthesized and pharmacologically evaluated. The key step in the synthesis is the formation of the bicyclic system 8 by consecutive nucleophilic substitution of the chloropropionamide 7 with primary amines and intramolecular aminolysis. Both reaction steps require catalysis with the Lewis acid Ti(O-iPr)4. Homologation of the piperazine to the 1,4-diazepane ring results in a remarkable improvement of σ1receptor affinity and σ1/σ2selectivity. The 1,4-dibenzyl derivative 4a interacts with a Kivalue of 7.4nM with σ1receptors and shows a 53-fold selectivity for σ1receptors over σ2receptors.
