The Direct Approach: Enones possessing appendant allylic carbonates react directly with diorganozinc reagents in the presence of zinc diiodide [ZnI 2 ] to provide 5‐ and 6‐membered ring products of tandem or domino conjugate addition‐cycloallylation in good to excellent yield. In a related copper‐free transformation, allylic carbonates are found to engage in direct allylic substitution with diorganozinc reagents.
