A liquid-phase split-type synthesis of all the stereoisomers of dendroamide A, which exhibits multidrug-resistance reversing activity, has been carried out. The key to the concise synthesis was the fluorous-Fmoc protection strategy of each of the starting materials (D- and L-alanine and D- and L-valine). By using the fluorous-Fmoc encoding method, the target stereoisomers were effectively synthesized
树酰胺 A 的所有立体异构体的液相分离型合成已进行,该立体异构体具有多药耐药逆转活性。简洁合成的关键是每种原料(D-和L-丙氨酸以及D-和L-缬氨酸)的氟-Fmoc保护策略。通过使用 fluorous-Fmoc 编码方法,目标立体异构体可以在比相应的线性合成路线更少的步骤中有效地单独合成。
