Homoerythrina alkaloid synthesis

In the intervening 13 years the subject has expanded dramatically over 60 compounds are now classified as Erythrina alkaloids, and the structures of most of these have been deduced from a combination of mass spectral fragmentation analysis, H-NMR spectral interpretations, and chemical correlations with alkaloids of known structures. Some unusual alkaloids have been obtained from certain Cocculus species and a new, as yet small, subgroup, the Homoerythrina alkaloids, has been recognized. The biosynthetic pathway from tyrosine through the aromatic bases to the ery-throidines has been elucidated, and some significant advances have been made in methods of total synthesis. Reviews of the Erythrina alkaloids since 1966 have appeared (3-6).
