Biomimetic synthesis cultivates yellow poppy pigment
Cascade process that fuses indole with orientalin verifies biosynthesis of nudicaulins
Scientists have reported the first total synthesis of the pigments responsible for the yellow colour in Iceland poppies, eight decades after they were originally isolated. The syntheses mimic the unique cascade processes that happen in poppies and by generating the pigments in excellent yields they open the door to colour–scent studies.
