Li, Chuang-Chuang published the artcileSynthetic 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, Computed Properties of 4141-48-4, the publication is Journal of Organic Chemistry (2006), 71(18), 6892-6897, database is CAplus and MEDLINE.
An efficient intramol. Diels-Alder (IMDA) strategy for the construction of the [5-7-6] tricyclic core I of guanacastepenes has been developed from cis- and trans-1,3-butadiene-tethered 4-oxopent-2-ynoic acid Et esters II and III. This method facilitates the synthesis of C8-epi-guanacastepene O IV in a very efficient manner.
