- Synthesis of paddlanes possessing cyclophane shaft and cyclobutane blades
-
1,2- And 1,2,4,5-paddlanes were successfully prepared by the intermolecular [2 + 2] photocycloaddition of o-divinyl- and 1,2,4,5-tetravinylbenzenes, respectively. On the other hand, no desired paddlanes were obtained from p-divinyl- or 1,2,3-trivinylbenze

- INTRAMOLECULAR (2 + 2) PHOTOCYCLOADDITION. 6. SYNTHESIS AND PROPERTIES OF OXACYCLOPHANES
-
Several oxacyclophanes were prepared by a new photocyclization of styrene derivatives.Cyclophanes 2d and e underwent C-O bond cleavage and gave olefin 6a and b by subsequent transformations, respectively.
