The hydrophobic side chain of scyphostatin was synthesized by a convergent synthetic pathway. The key reactions were the enzymatic asymmetric acetylation of a meso-diol, construction of the C12′–C13′ trisubstituted E-olefin moiety by Negishi coupling, and construction of the (2′E,4′E ,E,6′E)-triene moiety by Horner–Wadsworth–Emmons olefination.
scyphosstatin的疏水侧链是通过聚合合成途径合成的。关键反应是内消旋二醇的酶促不对称乙酰化,通过 Negishi 偶联构建 C12'-C13' 三取代的 E-烯烃部分,以及构建 (2'E,4'E ,E,6'E)霍纳-沃兹沃思-埃蒙斯烯化的-三烯部分。
