The dienone protostephanone (3) is synthesised by phenol coupling or by Pschorr cyclisation from readily prepared tetrahydroisoquinolines, and the corresponding dienols (17) and (18) are converted by rearrangement, fragmentation, and reduction into protostephanine (4). This sequence mimics the natural pathway to the alkaloid.
通过苯酚偶联或通过Pschorr环化反应从容易制备的四氢异喹啉合成二烯酮原香精酮(3),然后通过重排,裂解和还原将相应的二烯醇(17)和(18)转化为原香精素(4)。该序列模拟了通往生物碱的天然途径。
