The synthesis and free energies are reported for 10 new hemispherands (1, 2, 4, 6, 7-9, 11-13) binding alkali metal and ammonium picrate salts at 25 deg C in CDCl3 saturated with D2O.These hemispherands possess the general structure I, in which two 4-subs

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
