Abstract

A unified and bioinspired oxidative cyclization strategy was used in the first total syntheses of naturally occurring 12-epi-hapalindole Q isonitrile, hapalonamide H, deschloro 12-epi-fischerindole I nitrile, and deschloro 12-epi-fischerindole W nitrile, as well as the structural revision of the latter. Hapalindoles H and Q were also synthesized.
