Biomimetic synthesis of nudicaulins I and II, yellow pigments from the Iceland poppy Papaver nudicaule

Abstract

Indole and the anthocyanin orientalin proceed through a unique cascade sequence that leads to nudicaulins I and II in 92% yield. This biomimetic synthesis confirms the biosynthesis proposal for these structurally unprecedented flavoalkaloids that play a key role in the colour range displayed by the Iceland poppy.
