Daemonorops draco, one of the sources of the ancient resin known as “dragon's blood”. We present a short synthesis that clarifies their relative configurations and sheds light on their origin in Nature. This synthesis features biomimetic cascade reactions that involve both ionic and radical intermediates. The biogenetic relationships between dracorhodin, the dracoflavans C, and the dragonbloodins A1 and
龙血精是一对复杂的类黄酮三聚体,已从棕榈树Daemonorops draco中分离出来,而Daemonorops draco是一种被称为“龙血”的古老树脂的来源。我们提出了一个简短的综述,阐明了它们的相对构型,并阐明了它们在自然界中的起源。该合成的特征是仿生级联反应,涉及离子和自由基中间体。讨论了dracorhodin,dracoflavans C和Dragonbloodins A1和A2之间的生物遗传关系。
