The transformation of cyclic hemiacetals (lactols) into lactones has been achieved by Cu-catalyzed aerobic C[BOND]C bond cleavage in the presence of N-hydroxy phthalimide (NHPI). The present process is composed of a multistep sequence including a) formation of exo-cyclic enol ethers by dehydration;...
