Novel cationic rearrangements of the [3.3.3]propellane system: application to the total synthesis of decarboxyquadrone
Abstract
The first carbonium ion rearrangement of the [3.3.3]propellane ring system to the tricyclo[4.3.2.01,5]undecane and tricyclo[6.3.0.01,5]undecane skeletons has been observed and extended to the total synthesis of the biologically active compound decarboxyquadrone.
