Article abstract of DOI:10.1021/jo00388a018

The effect of variation of the rigid part of the parent Cram hemispherand 1a on the preorganization of the macrocyclic cavity has been studied.Four novel 18-membered hemispherands (3,4a-c)have been synthesized via a novel multistep route using 2,6-di- and
