• Aldol condensations on a 3-alkylidene-2,5-diketopiperazine - synthesis of two marine natural products 

      Fairhurst, Magnus John E.; Muhammad, Zeeshan; Haug, Bengt Erik; Bayer, Annette (Peer reviewed; Journal article, 2018)
      The synthesis of two marine natural products containing a 3-alkylidene-6-arylidene-2,5-diketopiperazine scaffold by employing two consecutive aldol condensations starting with 1,4-diacetyl-2,5-diketopiperazine is reported. ...
