Detailed in this report are several new efficient synthetic approaches toward the natural product anti cancer agent varitriol, culminating in a concise total synthesis. A common theme for these routes is that they employ a new catalytic stereoselective vinyl oxirane ring expansion reaction, which provides rapid access to the common cis-2,5-tetrahydrofuran core. The combination of careful synthetic
详述本报告中是几个新的有效的合成向天然产物接近抗癌剂varitriol,以简明的全合成最终。这些路线的共同主题是,它们采用了新的催化立体选择性乙烯基环氧乙烷环膨胀反应,该反应可快速进入常见的顺式-2,5-四氢呋喃核。仔细的合成设计和适当的起始材料选择相结合,使这种新方法(乙烯基环氧乙烷环扩环)与母题(varitriol)完美地结合在一起。
