Novel Synthesis of Right Segment of Solanoeclepin A
摘要:
The highly strained tricydo[5.2.1.0(1,6)]decene skeleton of solanoedepin A was synthesized through two key C-C bond forming processes; thus, a Hg(TFA)(2)-mediated oxymercuration followed an intramolecular aldol reaction to B and a SmI2-mediated cydization of C between an aldehyde and an unsaturated ester to form the cydobutane D having a tricyclo[5.2.1.0(1,6)]dodecene.

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
