The 4-exo-dig and 5-exo-dig cyclocarbopalladations have been efficiently used to produce molecular complexity in a straightforward manner. Strained 1,2-cyclobutanediols are rapidly obtained under microwave irradiation in high yields. In many cases, the cyclocarbopalladation cascade reaction is associated with a 6 or 8p electrocyclic reaction. During the process of the 5-exo-dig cyclocarbopalladation on benzosuberone derivatives, an aromatic CH activation leads to vinylic substituted aromatics. Polycyclic skeletons of natural products of the family of Ophiobolin and Aleurodiscal can be prepared in few steps from simple starting material.
