The stereocontrolled synthesis of the highly strained, tricyclo[5.2.1.01,6]decene skeleton (C) of solanoeclepin A has been achieved through two key transformations: a [2,3]-Wittig rearrangement of allylpropargyl ether (A) to propargyl alcohol (B) having a trans-fused perhydroindane framework and the formation of the cyclobutane via a cobalt-mediated Hosomi–Sakurai type cyclization of an acetylene
通过两个关键的转变,实现了茄烯A的高张力三环[5.2.1.0 1,6 ]癸烯骨架(C)的立体控制合成:烯丙基炔丙基醚(A)的[2,3] -Wittig重排成炔丙基醇(B)具有反式融合的全氢茚满骨架,并通过钴介导的乙炔二钴六羰基络合物的Hosomi-Sakurai型环化反应形成环丁烷。
