Seven macrocyclic ethers containing 2,2′-substituted-1,1′-binaphthyl units as chiral barriers connected through different combinations of OCH2CH2OCH2-CH2O, O[CH2]5O, m-C6H4(CH2O)2 and 2,6-C5H3N(CH2O)2(substituted pyridyl) units complex differently with the enantiomers of the hexafluorophosphate salts of racemic methyl phenylglycinate and methyl valinate.
通过OCH 2 CH 2 OCH 2 -CH 2 O,O [CH 2 ] 5 O,m -C 6 H的不同组合连接的7个含有2,2'-取代的-1,1'-联萘单元作为手性屏障的大环醚4(CH 2 O)2和2,6-C 5 H 3 N(CH 2 O)2(取代的吡啶基)单元与外消旋苯基甘氨酸甲酯和缬氨酸甲酯的六氟磷酸盐的对映异构体不同。
