Synthesis of marine bisindole alkaloids, hamacanthins A and B through intramolecular transamidation-cyclization

The total syntheses of the marine bisindole alkaloids, hamacanthins were achieved by a novel transamidation-cyclization of N-(2-aminoethyl)-2- oxoethanamides to 3,5- and 3,6-disubstituted piperazinones.
