High specific activity (+)-amphetamine and (+)-methamphetamine were prepared by reductive dechlorination of (S)-(3′,5′-dichlorophenyl)-2-propylazide and (S)-2′6′-dichloromethamphetamine, respectively. While the latter was readily obtained by resolution of racemic 2′6′-dichloromethamphetamine using (+)-dibenzoyltartaric acid, the analogous amphetamine resisted all efforts to resolve it. Hence, the required chiral precursor was prepared by stereospecific total synthesis following methodology that had been previously developed in our Laboratories. The tritium labeled compounds had specific activity 30.1 Ci/mmol and 38.3 Ci/mmol, respectively. Copyright © 2009 John Wiley & Sons, Ltd.
高比活性的(+)-安非他命和(+)-甲基安非他命分别通过(S)-(3′,5′-二氯苯基)-2-丙基叠氮和(S)-2′6′-二氯甲基安非他命的还原脱氯制备。后者可通过使用(+)-酒石酸二苯酯对消旋的2′6′-二氯甲基安非他命进行拆分而容易获得,而对类似安非他命的拆分尝试均告失败。因此,所需的手性前体是通过在我们实验室先前开发的方法指导下进行立体选择性全合成制备的。氚标记的化合物分别具有30.1 Ci/mmol和38.3 Ci/mmol的比活度。版权所有 © 2009 约翰威立父子出版公司。
