Lewis-acid catalyzed prenylation of aromatic amines with prenyl diisopropyl phosphate gave N-prenylated amines, whereas nitrogen-containingaromatic heretocycles gave nucleus prenylated products.
Pyrrole and indoles react smoothly with alkyl halides such as allyl bromide, prenyl bromide, crotyl bromide and propargyl bromide in the presence of zinc metal in THF to afford the corresponding 3- and 2-alkyl pyrrole and 3-alkyl indole derivatives in good yields with high regioselectivity.

Non-activated allyl alcohols are utilized as allylating agent for thiocarbamate-directed allylation of pyrrole and indole. The synthetic methodology is accompanied by advantages like silver-free conditions and generates water as the by-product. A wide range of substituted pyrroles and indoles along with several structurally different allyl alcohols took part in the reaction. Among notable examples
