The preparation of calix[n]naphthalenes fromderivatives of 2,7-dihydroxynaphthalene is described. 1,8-Dialkyl substitution is used to direct the regiochemistry of the acid-catalyzed condensation reactions. Acyclic peri substituents lead to a 3,5-linked calix[3]naphthalene, whereas cyclic peri substituents give predominantly a calix[5]naphthalene with the corresponding 3,6-linkage. The 3,6-linked calix[4]naphthalene
