An unprecedented 24-N-imidazolyl steroidal alkaloid, amaranzole A, was isolated from a tropical sponge, Phorbas amaranthus. The structure was solved by interpretation of MS, NMR, including a novel exciton-coupled CD spectrum due to an allyl imidazole, and comparison with model compounds.
从热带海绵Phorbas amaranthus中分离出了一种前所未有的24-N-咪唑基甾体生物碱——苋唑A。通过对质谱、核磁共振谱(包括由于烯丙基咪唑产生的新型激子耦合圆二色光谱)的解析,并与模型化合物进行比较,确定了其结构。
