Star quality: Goniopectenoside B, a minor asterosaponin from starfish Goniopecten demonstrans with antifouling activity, has been synthesized in a convergent 21 steps and in 4.3 % overall yield starting from adrenosterone. This represents the first synthesis of a complex asterosaponin, which are ubiquitous and characteristic in starfish as defense chemicals (see figure).
明星品质:人参皂甙B(一种来自海星人魔皂甙的反式除垢剂,具有防污活性)已经聚合了21个步骤,从肾上腺素开始的总收率为4.3%。这代表了复杂的星形皂苷的首次合成,该蛋白在海星中作为防御化学物质无处不在且具有特征性(见图)。
