Total Synthesis of (±)-Terpestacin and (±)-11-epi-Terpestacin
摘要:
The total synthesis of racemic terpestacin and 11-epi-terpestacin using the allene ether Nazarov reaction as the key step is described. All stereochemistry is derived from the stereogenic carbon atom that is formed during the Nazarov reaction.

A stereocontrolled total synthesis of (−)-terpestacin has been achieved starting from (R)-(−)-carvone as a chiral pool and (E,E)-farnesol via a highly convergent approach. Thus, (R)-(−)-carvone was transformed into the cyclopentanone segment through a series of high yielding operations with the proper setup of all the stereochemical centers while (E,E)-farnesol was converted into the other requisite
