molecule is presented, and the synthesis of the key unit 2 required for the projected construction is described. The essential elements of the design included face to face oriented macrorings spaced by rigid trans-fused oxanes. The strategy combines conformational predictability of C-linked oxanyl systems and ring-closingmetathesis for the synthesis of crownethers with engineerable ion-binding abilities
