pathway involving decyanation chemistry for the synthesis of pure alkyl α,ω-dienes in quantitative yields is presented. Prior methodologies for the preparation of such compounds required 6−9 steps, sometimes leading to product mixtures resulting from olefin isomerization chemistry. This isomerization chemistry has been eliminated. Deuteration labeling and structural mechanistic investigations were completed
The intramolecular carbocyclization of secondary organozinc derivatives allows the preparation of cis-substituted cyclopentylmethylzinc derivatives in an easy and straightforward way.
