Abstract
Total syntheses of the antirhine alkaloids are described. The cyanide-catalyzed imino-Stetter reaction of the aldimine derived from ethyl 2-aminocinnamate and 4-bromopyridine-2-carboxaldehyde provided a 2-pyridinyl substituted indole-3-acetate, which was further converted into the corresponding indoloquinolizidinium intermediate through C-ring formation. Subsequent trans-selective installation of the homoallylic alcohol side-chain at C-15 in the resulting indoloquinolizidinium allowed the total syntheses of antirhine and its known epimer.
