Abstract
The two novel tricyclic C~10~H~16~ compounds antiβ and synβtricyclo [4.2.1.1^2,5^]β decane (16 and 17, respectively) were synthesized starting either from the photodimer 2 (anti) or the two cycloaddition products 8 (anti) and 9 (syn).

## Abstract A synthesis of tricyclo [4.2.2.2^2,5^]dodecane (**19**), a novel tricyclic C~12~H~20~ compound, is described. The key intermediate ketone **13** was prepared either from the C~10~βphotodimer **1** of cyclopentadienone or the C~11~βcycloaddition products **11** and **12**. **13** was als
## Abstract Sensitized irradiation (Ξ» = 254 nm) of the title compounds **2 a** and **2 b** in benzene affords the tetracyclic oxetanes **3 a** and **3 b**. The irradiation of **2 c** under similar conditions yields equal amounts of **3 c** and the cyclopentadiene derivative **5**. The formation of
