A Short Path to Erythrina Alkaloid Derivatives

摘要

Erythrina alkaloids which display a variety of biological activity including hypnotic and CNS activity have drawn attraction for the synthesis over the years. Some of the recent strategies on the construction of the core spirocyclic structure include intramolecular cyclization reactions such as radical cyclizations, electrophilic substitution cyclizations oniV-acyliminium intermediates or Pummerer-induced cyclizations, Heck reactions, and anionic substitution reactions.
