An improved synthesis of (-)-5,11-dideoxytetrodotoxin

We describe an improved synthesis of (-)-5,11-dideoxytetrodotoxin from an enone, which was used for synthesis of tetrodotoxin and its analogues in this laboratory. One of the major modifications was to establish a two-step guanidinylation of trichloroacetamide of a highly functionalized intermediate, which allowed us to prepare 15N2-labeled 5,11-dideoxytetrodotoxin for biosynthetic investigations.
