胆紫素的形成和八乙基卟啉的光氧化

Formation of Biliviolin and Photooxygenation of Octaethylporphyrin

红藻和蓝绿藻中的藻红胆素是光合作用中的天线色素,起着重要的传递能量的作用。藻红胆素和胆紫素在线型四吡咯化合物中同属于胆二烯a,b类,因此胆紫素可以作为藻红胆素的模型化合物或合成藻红胆素类似物的中间体。

Octaethylporphyrin-magnesium (MgOEP) was photooxygenated to yield a brownproduct----1-formyloctaethylbiliverdin 1 which could coordinate with Zn^(2+) and then bepurified through chromatography. 1 was oxidated by silver nitrate to give 15-oxo-19-for-myloctaethylbiliviolin 2.
