One, two, three selective oxidations are the key steps in the atom‐economic first total synthesis of the natural ten‐membered lactone cephalosporolide G and its C‐3 epimer (see scheme). They have been synthesised in only seven or eight steps starting from the natural phenol (R)‐rhododendrol, which contains all the carbon atoms present in the final targets.
