用25,27-二(2-溴乙氧基)-26,28-二羟基-5,11,17,23-四叔丁基杯[4]芳烃与光学纯的(1S,2R)-(+)-2-氨基-1,2-二苯基乙醇合成了手性杯[4]芳烃氨基醇2. 2能在极性的甲醇中组装成二聚体,通过1H NMR滴定测定其结合常数Ka为34.7 M-1,并提出了自组装机理.

关键词: 手性杯[4]芳烃, 自组装, α,β-氨基醇, 二聚体

Chiral calix[4]arene amino alcohol 2 was synthesized by the reaction of 25,27-di(2-bromoethoxy)-26,28-dihydroxy-5,11,17,23-t-butylcalix[4]arene with optical pure (1S,2R)-(+)-2-amino-1,2-diphenylethanol. 2 can form 1:1 dimer by self-assembly in d-methanol and the association constant of the dimer is 34.7 M-1 determined by 1H NMR titration.

Key words: chiral calix[4]arene, self-assembly, α,β-amino alcohol, dimer
