Synthesis of several members of the 9-oxaergoline ring system is presented. Both the C/D cis and the C/D trans isomers of 4,6,6a,8,9,10a-hexahydro-7-ethyl-7H-indolo[3,4-gh] [1,4]benzoxazine were prepared, and the C/D trans isomer was resolved into its optical isomers. The enantiomer having the highest affinity for the [3H]apomorphine binding site, (-)-trans-6-ethyl-9-oxaergoline [(-)-6b], was shown
介绍了9-氧杂麦角环系统几个成员的合成。制备了4,6,6a,8,9,10a-六氢-7-乙基-7H-吲哚并[3,4-gh] [1,4]苯并恶嗪的C / D顺式和C / D反式异构体,并将C / D反式异构体拆分为其旋光异构体。对[3H]阿扑吗啡结合位点具有最高亲和力的对映体(-)-反式-6-乙基-9-氧杂麦角碱[(-)-6b]具有与天然麦角灵相同的绝对构型,即,6aR,10aR。体内和体外药理学评估表明,这些9-氧杂麦角碱具有有效的多巴胺激动剂特性。
