Preparation of homochiral phenolic crown ethers containing para-substituted phenol moiety and chiral subunits derived from (S)-1-phenylethane-1,2-diol: Their chiral recognition behaviour in complexation with neutral amines

Article abstract of DOI:10.1016/S0957-4166(97)00047-5

Crown ethers 1-6 containing two chiral subunits derived from (S)-1-phenylethane-1, 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 recog
