The structures of the related alkaloids amurine (IV) and nudaurine (V) are elucidated mainly from spectroscopic studies. Supporting evidence for these structures is provided by the Hofmann degradation of amurine to 2-hydroxy-3-methoxyphenanthrene and by the rearrangement of amurine, under acidic conditions, to the phenanthrene XIV (R = H). Similarly, nudaurine with acid is shown to afford the phenanthrene
主要从光谱学研究中阐明了相关生物碱金嘌呤(IV)和nudaurine(V)的结构。这些结构的支持证据是通过将霍夫曼将霍夫曼降解为2-羟基-3-甲氧基菲以及在酸性条件下将氨氮重新排列为菲XIV(R = H)来提供的。类似地,显示出带有酸的尿嘧啶可提供菲XVIII(R = H)。讨论了IV和V的生物起源。
