Nudicaulins, yellow flower pigments of Papaver nudicaule: revised constitution and assignment of absolute configuration.
The constitution of the aglycon of nudicaulin has been revised to be a pentacyclic indole alkaloid. The relative and absolute configurations of the two diastereomers, nudicaulins I (3a) and II (3b),… Expand
