Three distinct synthetic routes to the 2-prenyl tryptophan core skeleton of tryprostatins and their total syntheses are described. The strategies include a traditional gramine-mediated coupling reaction, Fuerstner indole synthesis, and our radical-mediated indole synthesis from o-alkenylphenyl isocyanide. The establishment of reliable conditions for the radical-mediated construction of indoles via a low-temperature radical initiator V-70 (2,2′-azobis(4- methoxy-2,4-dimethylvaleronitrile)) led to the highly efficient syntheses of tryprostatins A and B.

Spirotryprostatin B was synthesized in eight steps, utilizing an efficient palladium-catalyzed prenylation reaction to construct the quaternary C3 stereocenter. The decarboxylation-alkylation of a series of substituted β-keto esters is described, demonstr
