New syntheses of the alkaloids eudistomin T and S are described. The key step,formation of the 1-phenylacetyl fl-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 av

A stereospecific synthesis of both enantiomers of the marine alkaloid eudistomin X using the amino acid chiral pool is achieved. Comparison of 1 H and 13 C NMR chemical shifts of the synthetic product as either the free base, mono-salt or disalt with those reported for the natural product establishe
