A semisynthetic method of preparing neosaxitoxin from cultures of the dinoflagellate Gymnodinium catenatum is described. The scalable method includes the reductive desulfonation of an unresolved mixture of toxin C3 and toxin C4 and mild acid hydrolysis of the resulting gonyautoxin 6 (GTX6) to provide the neosaxitoxin.
