An enantioselective synthesis of the 6-nor-derivative 3 of the antiviral macrocyclic lactam fluvirucinin B1 (2) is presented. Key steps are two regioselective ring opening reactions of chiral epoxides, and a ring-closing metathesis with Grubbs’ catalyst. The choice of appropriate protective groups was essential for the success and efficiency of the synthesis.
本文展示了一种对映选择性的合成抗病毒大环内酯流病毒素B1(2)的6-去硝基衍生物3。关键步骤包括两个手性环氧化物的区域选择性开环反应,以及使用Grubbs催化剂的环闭合夺取反应。选择合适的保护基团对于合成的成功和效率至关重要。
