This paper is dedicated to Prof. Guoqiang Lin on the occasion of his 80th birthday, for his great contribution to organic chemistry in China.
Inherently chiral calix[4]arenes were separated by condensation with chiral auxiliary (S)- and (R)-1-phenylethylamine using column chromatography on silica gel; subsequent derivatization with click chemistry furnished compounds with fluorescent properties that can be used for chiral recognition.
Key words
calix[4]arene - inherently chiral - click chemistry - fluorescent sensors - chiral resolution
