Abstract

Triethylborane promotes the Pd-catalyzed allylic alkylation of pyrroles with a variety of allylic alcohols to provide either C2 allylation products (α,α-, γ,γ-dimethylallyl alcohol and geraniol) or C2,C5 diallylation products (allyl alcohol, α-, β-, γ-methyl-, and α-, γ-phenylallyl alcohols) in good to excellent yields under mild conditions.
