A facile transformation of spirocyclic vinylcyclopropanes to titled bridged-alkenes is presented; this approach finds an application in the synthesis of natural product carbon framework of diverse nature such as that of precapnelladiene and muscone.
Two isomeric linear triquinanes, cis-transoid-cis- and cis-cisoid-cis-tricyclo[6.3.0.02,6]undecan-1-ols, were effectively synthesized by means of the modified Barbier cyclization.
