“…It is worth noting that more sterically congested substrates,such as those leading to the products 14 and 15 required longer reaction time and higher catalyst loading,thus suggesting that the ligation of the alcohol to the cerium center is crucial for this transformation. With respect to unsymmetrical substrates,ah igh degree of regioselectivity can be achieved in the CÀCbond b-scission step,asthe product derived from the most stable radical intermediate was exclusively observed in all cases (12)(13)(14)(15)(16)(17)(18). Notably,t he mild reaction conditions employed in this transformation allow expansive functionalgroup compatibility,a sd emonstrated by the highly efficient transformation of complex terpenoid-and steroid-derived cycloalkanols containing varied redox active functional groups and Lewis basic sites (14,(16)(17)(18).…”
