Efficient and rapid syntheses of various pyrrolizidine alkaloids via microwave synthetic protocols using monocrotaline from a natural source (Crotalaria spectabilis) are reported. Retronecine, hydroxydanaidal, and acetylated hydroxydanaidal (utilized in the chemical communication system of various insect species) were obtained. In addition, a continuous flow hydrogenolysis/hydrogenation approach to
据报道,通过微波合成方法,使用天然来源的苦瓜碱(猪屎豆),可以高效,快速地合成各种吡咯烷核生物碱。获得了逆转录神经素,羟基金丝和乙酰化的羟基金丝(在各种昆虫物种的化学通讯系统中使用)。另外,实现了连续流的氢解/氢化方法以直接获得铂炔,逆转录烯醇和脱氧维甲酸。
