Alkylation of the tetrahydroxy-tetraoxocalix[4]arene 5 with n-butyl bromide proceeds in a stereoselective fashion and affords exclusively a single atropisomer of the tetraoxocalix[4]arene tetrabutyl ether derivative. Reaction with MeLi followed by fourfold acid-catalyzed elimination of water affords the rigid calix[4]radialene 8. The crystal structure of 8 corroborated the proposed calixradialene structure and indicated an 1,3-alternate arrangement of the rings.
