Calix[4]arene analogs 4a and b were obtained in 15 and 13% yields, respectively, by intermolecular [2 + 2] photocycloaddition. The conformations of 4a and b are assigned to be 1,2-alternate form and cone one, respectively. The calix[4]arenes 5a and b having hydroxy groups were also obtained in 84 and 80% yields, respectively, by ether cleavage of 4, whose conformations are maintained by this transformation.
