Abstract

As diacyl olefin derivatives are known to be very reactive toward nucleophiles, and those with Z-configuration seem easy to change into E-isomers, we planned to protect the olefin part as a Diels-Alder adduct with cyclopentadiene and to regenerate it by retro Diels-Alder reaction at a final stage. Thus the enone L which is easily obtained by Dieis-Aider reaction of p-quinone with cyclopentadiene was chosen as a starting material. Triethylamine ...
