Abstract
[GRAPHICS] A concise synthesis of topsentin A (R-1 = R-2 = H) and nortopsentins B (R-1 = Br, R2 = H) and D (R-1 = R-2 = H) is described from oxotryptamine 5 via reduction of acyl cyanide 4, Regiospecific bromination of a cyanoindole aff orded 6-bromo-3-cyanoindole (10) as the major product.
