Abstract

Abstract: Five new spherands and three new hemispherands containing cyclic urea units have been designed and synthesized, and their binding properties have been examined. Formally, these macrocycles are composed by attaching to one another the following units: 2, 6-disubstituted anisyl, or A; 2, 6-disubstituted 4-methylanisyl, or A '; N, N-disubstituted tetrahydro-2-pyrimidinone, or U; 2, 6-disubstituted l-(allyloxy)-4-methyIbenzene, or A'a; 2, ...
