The fourfold bridged tricyclo[4.2.0.0 2,5 ]octa‐3,7‐diene derivative 3 reacts with diazomethane and m 1‐chloroperbenzoic acid ( m CPBA) to yield the monoadduct 5 in good and the bisadduct 4 in poor yield as well as the mono‐and bisepoxides 7 and 8 in good yields, respectively. Also the “mixed” product 6 is obtained. All five compounds are strained propellanes. The X‐ray crystallographic structure analysis of 8 reveals a distance of 2.812 Å between the epoxide rings.
