It has been a little over a year since the last synthesis-golf was posted. I have talked to orthocresol and would like to help revive the tag! A full FAQ post has been written on chemistry.meta.SE, explaining the premise of synthesis golf and the 'rules'. Please take a look at this before answering (if you haven't already).

Hyperielliptone HA is a phloroglucinol extracted by Wu et al1 in 2008. The compound is of particular interest because of its highly unique structure and demonstration of DNA oxidation inhibition.

Hyperielliptone HA


  • Your synthesis must involve a method for the preparation of the phloroglucinol core.

  • Your synthesis must be stereoselective; however, the stereocenter attached to the phloroglucinol core can be racemic. Bonus points if you can develop a stereoselective synthesis for this moiety!

  • All reagents must be available from Sigma Aldrich.

  • If you do not have time to complete the entire synthesis but have a clever idea for a specific moiety, feel free to share your answer.

  • $\begingroup$ HINT: This compound exist in two tautomeric forms. This might make conceptualizing this molecule a bit easier -- it's good to tackle a synthesis by looking at the molecule from multiple angles! $\endgroup$ – Eli Jones May 18 '20 at 9:07

    $\begingroup$ If you have not yet thought about it; maybe you would like to submit a synthesis. $\endgroup$ – Martin - マーチン May 24 '20 at 9:19
