Synthesis and Enantiomer Recognition of Dipodands and Crown Ethers Containing the 2,3:6,7-Dibenzobicyclonona-2,6-diene Residue as the Chiral Subunit

Article abstract of DOI:10.1246/bcsj.62.83

Five new optically active crown ethers and six optically active dipodands are reported.The crown ethers were synthesized by using (+)-(1S,4R,5S,8R)-2,3:6,7-dibenzobicyclo<3.3.1>nona-2,6-diene-4,8-diol and (+)-(1S,4R,5S,8R)-4,8-bis(hydroxymethyl)-2,3:6,7-d
