Azophenolic crown ethers (S,S)-1, (R,R)-2 and (S,S)-3 have been prepared in enantiomerically pure forms by using (S)-1-(1′-adamantyl)ethane-1,2-diol, (R)-3,3-dimethylbutane-1,2-diol and (S)-propane-1,2-diol, respectively, as chiral subunits, and the assoc

Homochiral 1-(1-adamantyl)ethane-1,2-diol (5) was prepared and its absolute configuration was determined to be (S)-(+)-5 by enzymatic and 1H n.m.r. spectroscopic methods.Using (S)-(+)-5 as a chiral subunit, the homochiral crown ether (+)-18 was synthesize
