Epoxides 1a,b, the probable bioprecursors of a serie of indoloterpene alkaloids, were synthezised from indole and farnesyl bromides through application of the Van Tamelen regiospecific epoxidation process to the derived N-acylindolines 14a,b.

Zinc triflate was found to be an effective reagent for the C3-alkylation of indoles by alkyl halides in the presence of Hunig's base and tetrabutylammonium iodide. This new method for indole alkylation proceeds by a S(N)1-like pathway, and is general for allylic, benzylic, and tertiary halides.
