Uh. Maier et Mh. Zenk, (S)-NORRETICULINE IS THE PRECURSOR FOR THE BIOSYNTHESIS OF ERYTHRINA ALKALOIDS, Chemical communications, (23), 1997, pp. 2313-2314
In contrast to previous assumptions, the isoquinoline alkaloid (S)-nor
reticuline is the biosynthetic precursor to Erythrina alkaloids and, f
urthermore, this precursor is asymmetrically incorporated into these s
pirocyclic alkaloids.
