An antitumor acetogenin, muconin, was synthesized through a coupling reaction of a THF–THP segment and a terminal butenolide. The key reactions include 6-exo cyclization of an epoxy tetraol, regioselective cyclization of hydroxy tosylate, and stereoselective reduction of an acyclic ketone adjacent to the 2,6-cis THP ring with Zn(BH4)2.
通过THF-THP链段与末端丁烯内酯的偶联反应合成了抗肿瘤产乙酸原素粘蛋白。关键反应包括环氧四醇的6- exo环化,羟基甲苯磺酸酯的区域选择性环化以及与Zn(BH 4)2相邻的2,6-顺式THP环的无环酮的立体选择性还原。
