Abstract
The stereoselective construction of functionalized bicyclo[5.4.0]undecene systems, found in many natural sesquiterpenes such as in the widdrane, guadalupane, and recently isolated guanacastepene families, is achieved by selective chemical transformations of a functionalized cycloheptanol arising from the MARDi cascade.
