and (6aR)-aporphine-1, 1, 10, 11-tetrol (16) have been prepared from natural (S)-bulbocapnine (4). For both compounds, the partial synthesis included racemic intermediates which have been resolved into their enantiomers. Both compounds 8 and 16 showed dopaminergic activity in rats, although to a lower extent than (R)-apomorphine (1) itself.
(6a R)-1,2-(亚甲二氧基)aporphine-10,11-diol(8)和(6a R)-aporphine-1,1,10,11-tetrol(16)是由天然(S)制备的-bulbocapnine(4)。对于这两种化合物,部分合成都包括外消旋中间体,这些中间体已拆分成对映异构体。化合物8和16在大鼠中均显示出多巴胺能活性,尽管程度低于(R)-阿扑吗啡(1)本身。
