New syntheses of the alkaloids eudistomin T and S are described. The key step, formation of the 1-phenylacetyl β-carboline, involves a tandem aza Wittig/electrocyclic ring closure process. The first synthesis of the alkaloid xestomanzamine A is achieved by coupling of a N-protected harmane, now available via aza Wittig/electrocyclic ring closure process, with a 5-lithioimidazole derivative.
