✦ Synopsis

Crown ethers 1--6 containing two chiral subunits derived from (S)-Iphenylethane-l,2-diol and a phenol moiety bearing an intra-annular OH group and an additional para-substituent have been prepared in enantiomerically pure forms and their enantiomer recognition behaviour in complexation with neutral amines has been examined by the I H n.m.r, spectroscopic method, t~) 1997 Elsevier
