Special Topic 6.6 Photochemical synthesis of cage compounds 

Highly strained cage compounds have long attracted considerable attention from both experimentalists and theoreticians.724 The most important structural component of cage compounds is very often a highly strained cyclobutane ring, which is easily accessible by a photochemical route.725 Cubane for its aesthetic beauty counts as one of the milestones in synthetic (photo)chemistry and structural organic chemistry.726 A
