The olefination of Boc-protected lactams was extended to pyrrolidinone using a modifiedJuliaolefination. We also demonstrates that exo-enamides can be easily transformed into indolizidine and this methodology was applied to the total synthesis of natural Indolizidine 209D.
使用改进的 Julia 烯化将 Boc 保护的内酰胺的烯化扩展到吡咯烷酮。我们还证明了外-烯酰胺可以很容易地转化为吲哚里西啶,并且该方法应用于天然吲哚里西啶 209D 的全合成。
