Significance
Marek and co-workers report a highly stereodivergent route to unsaturated acyclic fragments in good to excellent yields. The key step for this transformation is the oxidative palladium-catalyzed Heck coupling of aryl boronic acids with alkenylcyclopropyl carbinols.

Comment
Remarkably, by using this method, all four stereoisomers of similar scaffolds can be synthesized. Furthermore, in addition to various arylboronic acids, alkenyl triflates or heteroarylboronic acids can be employed in the Heck reaction.
