WebFeb 6, 2012 · Indole alkaloids are the chemotaxonomic markers of the Aspidosperma genera. Those that have the simplest plumeran skeleton are classified as the precursors of biosynthetic routes and the intermediates for several synthetic reactions. This work aims to review the 1H and 13C-NMR data, up to 2011, describing the skeleton of 35 different … WebAlkaloids and derivatives [C0000279] ClassyFire class: Plumeran-type alkaloids [C0002672] ClassyFire subclass: Plumeran-type alkaloids [C0002672] ClassyFire direct parent: Aromatic heteropolycyclic compounds: SMILES:
