Treatment of germacrone (1) with different electrophiles, and of its epoxyderivativesgermacrone‐4,5‐epoxide (2), germacrone‐1,10‐epoxide (3) and isogermacrone‐4,5‐epoxide (4) with Brönsted/Lewis acids and TiIII, gives rise to a great structuraldiversity. Thus, by using a maximum of two steps, the production of more than 40 compounds corresponding to 14 skeletons is described. Computational calculations
