| Abstract
| - The tandem catalytic cyclization−rearrangement of 1,ω-dien-3-ols by palladium(II) produces differenttypes of products, depending on the structure of starting material. The pinacol rearrangement,benzannulation, and oxy-Cope rearrangement are major pathways of transforming the putative σ-alkylpalladium carbocation. Turnover of the cyclization is achieved by β-hydride elimination and reoxidationof palladium with benzoquinone. The overall course of the reaction is very sensitive to small changes inthe substrate structure.
