Vinylogous trifluoromethyl amide

The naturally occurring sulfonamide (-)-altemicidin is the first 6-azaindene monoterpene alkaloid isolated as a metabolite of microorganisms. A.S. Kende utilized the Polonovski-Potier reaction in the key step to introduce the carbamoyl enamine functionality. The tertiary amine was oxidized to the A/-oxide by H2O2 followed by treatment with excess TFAA to afford the desired vinylogous trifluoromethyl amide. [Pg.357]

Vinylogous trifluoromethyl amides. The Potier-Polonovski rearrangement of tertiary amine A(-oxides induced by (CFjCOjjO is frequently followed by trifluoroacetylation. This method is most suitable for the synthesis of (-)-altemicidin. ... [Pg.361]
