摘要
Chiral nitrogen-containing calix[4]arene was easily synthesized by the reaction of 25,27-di（2-bromoethoxy）- 26,28-dihydroxy-5,11,17,23-tetrakis（t-butyl）calix[4]arene with S-（-）-1-phenylethylamine in excellent yield, and showed good ability to recognize the enantiomers of mandelic acid and 2,3-dibenzoyltartaric acid. This finding has potential application to assay and separation of enantiomers of the carboxylic acids.
