T. Sugimura et al., SELECTIVE PREPARATION OF OPTICALLY PURE (R,R)-1,1' 5',1-TERNAPHTHALENE-2,2',6',2-TETRAOL - A NEW HIGHER HOMOLOG OF BINOL/, Tetrahedron letters, 39(36), 1998, pp. 6487-6490
As a new chiral auxiliary, the title compound of an enantiomerically p
ure higher homolog of BINOL was synthesized through stepwise formation
of optically pure 2,4-pentanediol tethers connecting three naphthyl g
roups by Mitsunobu reaction, oxidative intramolecular coupling, add el
imination of the tethers. (C) 1998 Elsevier Science Ltd. All rights re
