Addition of Me2CuLi, with in situ trapping by TMSCl, to Hagemann's ester derivative 13, furnished silyl enol ether 14. Mukaiyama-type cyclization of the latter compound gave the tricyclic derivative 15, structurally related to the taxane core.
在通过TMSCl原位捕获的情况下,将Me 2 CuLi添加到Hagemann的酯衍生物13中,得到甲硅烷基烯醇醚14。后一种化合物的Mukaiyama型环化产生三环衍生物15,其在结构上与紫杉烷核有关。
