A new tandemcatalytic process was designed and developed as a tool for the direct conversion of the widely available feedstock 2,7‐octadienol into an α,ω‐diester. This innovative auto‐tandem catalysis is atom efficient and consists of three consecutive palladium‐catalysed reactions: ether formation, ether carbonylation and alkoxycarbonylation. By using the design of experiments (DoE) approach, significant

[reaction: see text]. An alkylative titanium-mediated cyclization reaction of 1,3-diene-tethered carboxylic esters has been developed by employing an in situ generated titanacyclopropane intermediate to afford trans-2-alkenyl cyclohexanols.
