  Synthetic Study of 1,3-Butadiene-Based IMDA Approach to Construct a [5−7−6] Tricyclic Core and Its Application to the Total Synthesis of C8-epi-Guanacastepene O

  摘要：

  An efficient intramolecular Diels-Alder (IMDA) strategy for the construction of the [5-7-6] tricyclic core (18) of guanacastepenes has been developed from cis-and trans-1,3-butadiene-tethered-4-oxopent-2- ynoic acid ethyl esters 10 and 11. This method facilitates the synthesis of C8-epi-guanacastepene O (36) in a very efficient manner.
