The first synthesis of clusiparalicoline A, a prenylated and geranylated biphenyl compound isolated from the roots of Clusia paralicola, has been achieved by applying the sequential palladium-catalyzed Stille and Suzuki reactions to the formation of all the CC bonds on electron-rich aryl bromide and triflate. Clusiparalicoline A has been found to exhibit a potent neurite outgrowth promoting activity
clusiparalicoline A的第一合成,从根分离的异戊二烯化和geranylated联苯化合物Clusia paralicola,一直通过将连续的钯催化的Stille和Suzuki反应的所有CC键的形成上的富电子的芳基实现溴化物和三氟甲磺酸。已经发现,在胎儿大鼠皮层神经元的原代培养物中,Clusiparalicoline A在1.0μM时表现出有效的神经突生长促进活性。
