Auranthine, isolated in 1986 from Penicillium aurantiogriseum, is a fungal benzodiazepine. Through the successful total synthesis of (±)-auranthine, we confirmed the refined structure of natural (−)-auranthine. We established that natural (−)-auranthine is a fused quinazolino benzodiazepine dione 1 featuring an acyclic aliphatic nitrile moiety, thereby disproving the proposed structure 2.
Auranthine 于 1986 年从Penicillium aurantiogriseum中分离出来,是一种真菌苯二氮卓类化合物。通过(±)-金红素的成功全合成,我们确认了天然(−)-金红素的精细结构。我们确定天然 (−)-auranthine 是一种稠合喹唑啉苯二氮卓二酮1 ,具有无环脂肪腈部分,从而反驳了所提出的结构2 。
